The Chinese government also has other sources of income:
1. Land sales. This is a major one especially in big cities
2. State-owned enterprises. These are immensely profitable because they are often oligopolies. Imagine the US government owning Goldman Sachs, Morgan Stanley, AIG, Citigroup, Bank of America, JPMorgan Chase, Wells Fargo, Fidelity, AT&T, Verizon, Comcast, T-Mobile, Exxon Mobile, Chevron, ConocoPhillips, Philip Morris, etc etc
