Several major banks, including the 'Big Four' state-owned banks and others like China Merchants Bank, were also strategic investors.

Furthermore, Wuhan Yibapai Ling Enterprise Management Co., Ltd., a wholly-owned subsidiary of Xiaomi Technology, also saw substantial gains. The company's stake, acquired for approximately 158 million yuan, was valued at over 894 million yuan by the market close, yielding a profit of approximately 736 million yuan. This translates to a paper profit of nearly 717 million yuan for Xiaomi Chairman Lei Jun.

ChangXin Technology's debut also set multiple A-share records. It became the first tech stock to have an opening market value exceeding 3 trillion yuan, topped the A-share market capitalization rankings, and was the first stock to surpass 100 billion yuan in daily trading volume within its first hour, accompanied by an over 50% turnover rate.
