When logging into the Internet voting platform to vote for the first time, investors need to complete shareholder identity authentication. For specific operations, please see the instructions on the Internet voting platform website.

In order to better serve the majority of small and medium-sized investors, we ensure that small and medium-sized investors who are willing to vote can participate in the meeting and vote in a timely manner. The company plans to use the reminder service (i.e. "one-click call") provided by SSE Information Network Co., Ltd. to proactively remind shareholders to participate in the meeting and vote based on the shareholder list on the equity registration date through smart text messages and other forms, and proactively push meeting invitations, proposal status and other information to each investor. After receiving the smart text message, investors can vote directly according to the prompts in the "User Manual of One-Click Online Voting Service for Listed Company Shareholders Meetings" (download link: https://vote.sseinfo.com/i/yjt_help.pdf). In case of congestion, etc., they can still vote through the original trading system voting platform and Internet voting platform.

(2) For a shareholder holding multiple shareholder accounts, the number of exercisable voting rights is the total number of common shares of the same category and preference shares of the same variety held by all shareholder accounts under his or her name.

Shareholders holding multiple shareholder accounts who participate in online voting at the shareholders' meeting through the Exchange's online voting system can participate through any of their shareholder accounts. After the voting, it shall be deemed that all ordinary shares of the same category and preferred shares of the same variety under all shareholder accounts have voted with the same opinion.

If a shareholder holding multiple shareholder accounts votes repeatedly through multiple shareholder accounts, the voting opinions of the same class of ordinary shares and the same type of preferred stocks under all shareholder accounts shall be based on the first voting results of each class and type of stocks respectively.
