In China's official system, 81% of direct relatives are employed in finance, energy, and other franchising sectors, creating a closed loop of "power in the front office, wealth in the back office." 72% of China's wealthy have completed asset inheritance through offshore trusts before their children turn 25, which is a more covert mechanism for wealth perpetuation than the hereditary system for civil servants. Elite children in China develop problem-solving thinking at the primary school stage, while 74% of lower-tier students' thinking remains at the level of executing instructions, which is a more brutal divide than the housing market. Lower-class individuals lack awareness of the rules for upward mobility, making it difficult for them to find paths and methods; even with more knowledge, breaking the barriers of class is challenging.
