It's simple. The rent cost in big cities above the provincial level is too high, and many foods are snacks. How can we live on meager funds?
Besides, life in big cities is too fast. Even the owner of the food stall has no time to polish the snacks slowly. This problem does not exist in small cities. In slow life, both sellers and buyers can enjoy life slowly.
Slow life is not supporting laziness. Slowing down is not stalling. It is to let people find balance in their lives. Work is very important, but leisure time in life can't be ignored.
Life is beautiful. But if you live under high pressure and fast pace for a long time, you will easily lose the opportunity to enjoy a better life. Missed a good life. Only by slowing down and relaxing can we fully appreciate the beautiful life.
