        We are offering 8,300,000 American depositary shares, or ADSs. We anticipate the initial public offering price per ADS will be between US$9.00 and US$10.00.

        GGV Capital Select L.P., one of our principal shareholders, has indicated an interest in purchasing up to US$10.0 million worth of the ADSs being offered in this offering at the initial public offering price. Assuming an initial public offering price of US$9.50 per ADS, which is the mid-point of the estimated offering price range, the number of ADSs to be purchased by GGV would be up to 1,052,632 ADSs, representing approximately 12.7% of the ADSs being offered in this offering, assuming the underwriters do not exercise their over-allotment option. However, because the indication of interest is not a binding agreement or commitment to purchase, the underwriters could determine to sell more, fewer or no ADSs to GGV, and GGV could determine to purchase more, fewer or no ADSs in this offering. For additional information, see "Underwriting."

PROSPECTUS SUMMARY
The Offering

Offering price

  We currently estimate that the initial public offering price will be between US$9.00 and US$10.00 per ADS.

Use of proceeds

 

We expect that we will receive net proceeds of approximately US$68.5 million from this offering or approximately US$79.5 million if the underwriters exercise their over-allotment option in full, assuming an initial public offering price of US$9.50 per ADS, which is the midpoint of the estimated range of the initial public offering price, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Indication of Interest

 

GGV Capital Select L.P., one of our principal shareholders, has indicated an interest in purchasing up to US$10.0 million worth of the ADSs being offered in this offering at the initial public offering price. Based on this indication of interest, assuming an initial public offering price of US$9.50 per ADS, which is the mid-point of the estimated offering price range, GGV would purchase 1,052,632 ADSs, representing approximately 12.7% of the ADSs being offered in this offering, assuming the underwriters do not exercise their over-allotment option. However, because the indication of interest is not a binding agreement or commitment to purchase, the underwriters could determine to sell more, fewer or no ADSs to GGV, and GGV could determine to purchase more, fewer or no ADSs in this offering. See "Underwriting."

RISK FACTORS

Participation in this offering by our existing shareholder would reduce the available public float for our ADSs.

        GGV Capital Select L.P., one of our principal shareholders has indicated an interest in purchasing up to US$10.0 million worth of the ADSs being offered in this offering at the initial public offering price. Assuming an initial public offering price of US$9.50 per ADS, which is the mid-point of the estimated offering price range, the number of ADSs to be purchased by this shareholder would be up to 1,052,632 ADSs, representing approximately 12.7% of the ADSs being offered in this offering, assuming the underwriters do not exercise their over-allotment option. If such shareholder is allocated all or a portion of the ADSs in which it has indicated an interest in this offering and purchase any such ADSs, such purchase may reduce the available public float for our ADSs. As a result, any purchase of our ADSs by the existing shareholder in this offering may reduce the liquidity of our ADSs relative to what it would have been had these ADSs been purchased by other investors.

Because the initial public offering price is substantially higher than the pro forma net tangible book value per share, you will experience immediate and substantial dilution.

        If you purchase ADSs in this offering, you will pay more for each ADS than the corresponding amount paid by existing shareholders for their ordinary shares. As a result, you will experience immediate and substantial dilution of approximately US$8.02 per ADS (assuming that no outstanding options to acquire Class A ordinary shares are exercised). This number represents the difference between (i) our pro forma net tangible book value per ADS of US$1.46 as of June 30, 2018, after giving effect to this offering and (ii) the assumed initial public offering price of US$9.50 per ADS, the midpoint of the estimated initial public offering price range set forth on the front cover of this prospectus. See "Dilution" for a more complete description of how the value of your investment in the ADSs will be diluted upon the completion of this offering.

USE OF PROCEEDS

        We estimate that we will receive net proceeds from this offering of approximately US$68.5 million, or approximately US$79.5 million if the underwriters exercise their over-allotment option in full, after deducting underwriting discounts and commissions and the estimated offering expenses payable by us. These estimates are based upon an assumed initial public offering price of US$9.50 per ADS, which is the midpoint of the price range shown on the front page of this prospectus. A US$1.00 increase (decrease) in the assumed initial public offering price of US$9.50 per ADS would increase (decrease) the net proceeds to us from this offering by US$7.7 million, assuming the number of ADSs offered by us, as set forth on the front cover of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated expenses payable by us.

        The primary purposes of this offering are to create a public market for our shares for the benefit of all shareholders, retain talented employees by providing them with equity incentives and obtain additional capital. We plan to use the net proceeds of this offering as follows:

DILUTION

        Our net tangible book value as of June 30, 2018 was approximately negative US$64.3 million, or negative US$1.00 per ordinary share as of that date and negative US$2.00 per ADS. Net tangible book value represents the amount of our total consolidated assets, minus the amount of intangible assets, total consolidated liabilities and mezzanine equity. Dilution is determined by subtracting net tangible book value per ordinary share, after giving effect to the additional proceeds we will receive from this offering, from the assumed initial public offering price of US$9.50 per ADS, which is the midpoint of the estimated initial public offering price range set forth on the front cover of this prospectus, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

        Without taking into account any other changes in net tangible book value after June 30, 2018, other than to give effect to our sale of the ADSs offered in this offering at the assumed initial public offering price of US$9.50 per ADS, which is the midpoint of the estimated initial public offering price range, after deduction of the underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of June 30, 2018 would have been US$94.7 million, or US$0.63 per ordinary share and US$1.26 per ADS. This represents an immediate increase in net tangible book value of US$0.44 per ordinary share and US$0.88 per ADS to the existing shareholders and an immediate dilution in net tangible book value of US$4.12 per ordinary share and US$8.24 per ADS to investors purchasing ADSs in this offering.
