In China's official system, 81% of direct relatives are employed in sectors such as finance and energy, forming a closed loop of "power in the foreground, wealth in the background." 72% of China's wealthy complete asset inheritance through offshore trusts before their children turn 25, which is a more secretive mechanism for wealth perpetuation than hereditary civil service. Elite children in China develop problem-solving thinking at the elementary school stage, while 74% of students at lower levels remain at the level of executing instructions, creating a gap that is more brutal than the housing market for school districts. People at the bottom lack awareness of the rules for upward mobility, making it difficult to find paths and methods; even with more knowledge, it is hard to break through the barriers of class.
