2. The number of shares beneficially owned with shared voting power and shared dispositive power represents (i) 670,499 Class A Ordinary Shares directly held by JIANPING KONG LTD, a company incorporated in the British Virgin Islands, which is wholly owned by NlabsDAO Trust, a trust established under the laws of the British Virgin Islands and managed by Tricor Equity Trustee Limited, in which Mr. Jianping Kong is a settlor and investment manager, and (ii) 659,812 Class A Ordinary Shares directly held by Wlyl Ltd, a company incorporated in the British Virgin Islands, which is wholly owned by Lunyu Trust, a trust established under the laws of Singapore and managed by Teeroy Limited, in which Mr.Kong is a settlor and investment manager.

The rights of the holders of Class A Ordinary Shares and Class B Ordinary Shares are identical, except with respect to conversion rights (noted above) and voting rights. Each Class B Ordinary Share is entitled to 30 votes on all matters subject to vote at general meetings of the Issuer, whereas each Class A Ordinary Share is entitled to one vote.

3.
