Draft Registration Statement on Form S-1, submitted on June 26, 2018

Prospectus Summary, page 1

1.     We note your use of "IoT" and "IoT-enabled" throughout your prospectus
to describe your
       products, markets and financial results. We also note your disclosure on
page 1 that IoT
       products are IoT-enabled smart home products and your statement on page
5 that
       references to "IoT-enabled" are to Internet-of-things-enabled. Please
clarify how you
       define Internet-of-things (IoT), and thus "IoT-enabled." Clarify whether
these definitions

         apply across all contexts in which you use them.
2.       We also note your references to "household users" and "IoT products
shipped" throughout
         the prospectus. Please provide disclosure that explains how you define
and calculate these
         metrics. Also explain how these metrics are meaningful for
understanding your business
         or financial results.
3.       Please balance your disclosure to explain that you have only recently
expanded into
         selling IoT products and your own branded products.
4.       To provide further context regarding your relationship with Xiaomi,
please disclose the
         extent of Xiaomi's ownership in you. Also disclose that you generated
84.7% and 95.9%
         of net revenues in 2017 and 2016 from Xiaomi and its affiliates
primarily for the sales of
         Xiaomi-branded products. Disclose that these products consisted of
water purification
         systems, water purifier filters, and other complimentary products such
as kettles and water
         quality meters. Disclose the extent to which these products were
IoT-enabled as you
         define this term.
Corporate History and Structure, page 4

5.       Please disclose why you do not directly own your operations in China,
but use contractual
         arrangements with VIEs instead. Disclose that, if your PRC VIEs and
their
         shareholders fail to perform their obligations under the contractual
arrangements, you
         could be limited in your ability to enforce the contractual
arrangements that give you
         effective control. Further, if you are unable to maintain effective
control, you would not
         be able to continue to consolidate the VIEs' financial results with
your financial results.
         Disclose the percentage of revenues in your consolidated financial
statements that are
         derived from your VIEs. Disclose that you rely on dividends and other
distributions paid
         to you by PRC subsidiary, which in turn depends on the service fees
paid to your PRC
         subsidiary. Disclose the amount of dividends and fees that you expect
to collect. Disclose
         that this does not mean that you are able to have unfettered access to
your PRC
         subsidiary's and VIEs' revenues due to PRC legal restrictions on the
payment of
         dividends by PRC companies, foreign exchange control restrictions, and
the restrictions
         on foreign investment, among others.
6.       Please revise your corporate structure chart to indicate the structure
upon the completion
         of your initial public offering. Include the percentage ownership in
the registrant by
         public shareholders and material beneficial owners. Also disclose in
the chart the names
         of the individuals who have direct ownership and control over the
operating entities in
         China.

Risk Factors
Xiaomi is our strategic partner and our most important customer., page 12

7.       Please revise your final paragraph of this risk factor to clarify that
Xiaomi is now a public
         company by virtue of its recent Hong Kong listing. Revise, as
appropriate, to address that
         Xiaomi would consider in addition to the interests you have already
included, those of its
         public shareholders. Please revise to clarify briefly any process in
place to address
         apparent conflicts of interests.
8.       Please revise here, or under a separate risk factor heading, to
discuss the Business
         Cooperation Agreement with Xiaomi, specifically addressing its
expiration in August,
         2018, subject to automatic renewal. Please address that the agreement
may be terminated
         by Xiaomi with 30 days written notice prior to the expiration of the
then-current term.
         Please also discuss whether the Youpin Commission Sales Agreement
discussed at page
         142 may be extended beyond its December 31, 2018 expiration date.
Uncertainties with respect to the PRC legal system and changes in laws and
regulations in China
could adversely affect us., page 31

9.       Please clarify why the draft Foreign Investment Law may materially
impact the viability
         of your current corporate structure, corporate governance and business
operations if it is
         enacted.
We face certain risks relating to the real properties that we lease., page 38

10.      Please revise to specify how many ownership certificates or other
proof of leased
         properties have not been provided to the company by the relevant
lessors.
We will incur increased costs as a result of being a public company., page 47

11.      To the extent determinable, please provide an estimate of the
increased costs you expect to
         incur by virtue of being a public company.
Use of Proceeds, page 51

12.      We note that you intend to use the net offering proceeds for purposes
that relate to your
         operations conducted in the PRC. We also note that you are only
permitted under PRC
         laws and regulations to provide funding to your PRC subsidiary through
loans and capital
         contributions and to your VIEs through loans, subject to applicable
government
         registration and approval requirements. To provide context, please
quantify how much of
         your net offering proceeds would likely be available for investment in
your PRC
         operations. For example, quantify the current statutory limits on your
ability to loan or
         make capital contributions to your PRC subsidiary and to make loans to
your VIEs. Also
         disclose, if true, that you expect the IPO proceeds to be used in
China in the form of RMB
         and, therefore, your PRC subsidiary, VIEs and their subsidiaries will
need to convert any

         capital contributions or loans from U.S. dollars to RMB. Lastly,
discuss how long it would
         take and how likely it would be that you would receive the necessary
approvals to use the
         proceeds for the intended purposes.
Management's Discussion and Analysis of Financial Condition and Results of
Operations
Liquidity and Capital Resources, page 77

13.      Please disclose the amount of restricted assets of your PRC
subsidiaries as well as the
         unrestricted portion, or amounts otherwise available for transfer in
the form of dividends,
         loans or advances as of December 31, 2016 and 2017. We refer you to

14.      To provide context to this discussion, please disclose the percentage
of revenues in your
         consolidated financial statements that are derived from your Hong Kong
subsidiary, PRC
         subsidiary and your VIEs. Disclose that you rely on dividends and
other distributions paid
         to you by your PRC subsidiary, which in turn depends on the service
fees paid to your
         PRC subsidiary by your VIEs in China. Disclose the amount of fees paid
to your PRC
         subsidiary from your VIEs in the last two fiscal years. Disclose
whether you expect these
         levels to continue in the future.

network of over 700
         Viomi offline experience store, "including those in operation or under
renovation." Please
         disclose how many are in operation. Also clarify whether Viomi offline
experience stores
         are stand-alone stores or areas within other stores.
Intellectual Property, page 114

17.      Please revise to indicate the expiration dates of your patents, both
within and outside
         China. Given the number of patents the company holds, we would not
object to your
         indicating this data by disclosing the number of patents that expire
each year over the
         several year time period needed to cover them.
Regulations, page 120

18.      Please revise this section to specifically state how the regulations
discussed apply to the
         company and its affiliated entities and the extent to which the
company and its affiliated
         entities are in compliance with each regulation. As just a few
examples:

Experts, page 187

19.      We note on page 85 that your estimated fair value of the ordinary
shares was determined
         with the assistance of an independent valuation firm. While you are
not required to make
         reference to this independent third-party, when you do you should also
disclose the name
         of the expert and include a consent of the expert. Please revise
accordingly and advise us.
Report of Independent Registered Public Accounting Firm, page F-2

20.      Please have your registered public accounting firm revise their report
to indicate that the
         firm conducted its audits in accordance with the ``standards of the
Public Company
         Accounting Oversight Board (United States).   The reference in the
report to the
         ``auditing   standards of the Public Company Accounting Oversight
Board and "in
         accordance with auditing standards generally accepted in the United
States of America" is
         not consistent with the requirements of PCAOB AS 3101.

F-9

22.      Please describe in greater detail how the right to provide technical
and business support
         services in the exclusive consultation and service agreements conveys
the economic
         benefits to the Company. For example, explain whether the agreements
provide that
         the VIEs pay annual service fees to the WOFE in an amount that is
equivalent to all of
         their net income.
23.      We note your disclosure of the contractual agreements that provide the
Company with
         effective control over the VIEs, presumably enabling the Company to
have power to
         direct the activities that most significantly affect the economic
performance of the VIEs.
          Please clarify how the contractual agreements convey power to direct
the activities of the
         VIEs and what those powers entail.
