Why are China people so obsessed with "growing vegetables at home" that many people want to turn balconies and gardens into vegetable gardens?

Throughout the ages, China people are famous for growing vegetables. This practice has been passed down from generation to generation, as if growing vegetables is an innate skill of China people. Farmers either eat their own vegetables or support their families. Tao Yuanming resigned and retired to grow vegetables. Zhuge Liang grew vegetables in Nanyang in seclusion. Celebrities grow vegetables mainly as a political gesture, or even as a performance for everyone. Such as keeping a low profile, demonstrating diligently, or giving up on yourself in frustration. As far as the purpose of growing vegetables is concerned, the farmer's is the simplest and the celebrity's is the most complicated. Only Tao Yuanming, who voluntarily resigned and returned to his hometown to grow vegetables, is an exception ... China people have too many stories about growing vegetables. Nowadays, growing vegetables has become not only a fashion, but also an insistence of China people. During the epidemic, we all knew that we had to stay at home. Not only did we learn cooking skills, but many China people and celebrities also began to grow vegetables to kill time.
