According to personal library materials, Mo Yan said: Asking for help is like swallowing a three-foot sword, and leaning on people is as heavy as the sky. Always remember that when it rains, the ground slides, and you fall down and climb. If you want someone to help you, you have to change cigarettes for tea. In the real money society, the realization of any desire needs money as the backing. Therefore, the amount of wealth has become the most important criterion to measure a person's strength. So borrowing money is like swallowing a sword, and the next sentence is relying on people.
