Analysis of Baidu's Early Capital Structure and Relationships among Baidu Series Companies

Based on public information, I would like to conduct some analysis on the early capital structure of Baidu and the relationships between Baidu-related companies. I am very interested in capital operations, the use of corporate legal entity system for entrepreneurship, and enjoying the wealth of a company several decades or even hundreds of years in advance through its listing on the capital market. I hope everyone will actively exchange views on this topic!
