Some places pay attention to "eating spring vegetables at the vernal equinox", which is a kind of wild amaranth, also called "Artemisia annua", rather than a small mustard called "spring vegetables". The appearance is mostly bright green, thin, about the length of a palm. Spring vegetables are generally cooked with fish fillets, which is called "spring soup". There is a jingle: spring soup is dirty, liver and intestines are washed. A family, old and young, is safe and healthy.

According to the climate analysis of the vernal equinox, people should pay attention to maintaining the balance of yin and yang in health care and choose a diet that can keep the body function balanced according to their own actual situation.
