At present, the measures that can be seen are to reduce the interest rate of existing housing debts from 5% to 3%. As you said, the housing debts of many people are actually higher than the actual housing prices. This can only be said to be an inevitable result of the decline in real estate prices, because real estate prices cannot maintain an upward trend forever. This problem can only be solved gradually in the long future.
As for the issue of government funds, I can only say that we are very lucky. The rapid growth of exports has ensured that the government has ample funds. At the same time, if the idea of the government buying unsold houses on the market is really implemented, it will not cost much money, because the government can recover the houses at cost price.
