On November 10, 301311.SZ issued an initial public offering of shares and a preliminary inquiry and recommendation announcement on its listing on the gem. The number of shares to be issued is 60 million, accounting for about 25% of the total number of shares in the company after the offering. All of them are public offerings, and the company's shareholders do not sell shares. The total share capital after the IPO is 240 million shares.

The initial strategic placement investors are subsidiaries of sponsor institutions, with an initial strategic placement of 3 million shares, accounting for 5 per cent of the total. The difference between the final placing quantity and the initial placing quantity of strategic investors is partly transferred back to the offline offering.
