All countries that have a good market economy are due to better legal order. In fact, it is not difficult to establish a market. Once liberalized, people are driven by interests and the market can be formed quickly. However, once an unordered market is formed, It is very difficult to rectify it again. This sentence supports an argument, namely:. ['To establish a market economy system, we must attach great importance to the construction of the legal system.', 'Market regulation is an "invisible hand", and the market is spontaneously in a stable and balanced state.', 'The advantage of a market economy is that it enables people to be driven by their interests, thus motivating people.', 'The market can only be formed by relying on the legal system.']
