In ancient times on the mainland, there has always been a custom of the first seven, and even in many areas of modern times, there are still such rituals, and this custom has also been handed down.
As the name suggests, the first seven means that the body should be parked for seven days after the death of the person, and it is believed that the soul of the deceased will go home on the first seven to see the last time.

The act of preparing a meal for the family before the soul of the deceased returns may sound amazing, but why is it still used in some places today? In the ancient Spring and Autumn Period and the Warring States Period, there was a bizarre resurrection of the dead. The most critical figure in this resurrection of the dead is Bian Que. Bian Que must be no stranger to everyone, he has appeared in books and TV series "Legend of the Divine Doctor", he is a very famous doctor in the Spring and Autumn and Warring States periods. However, Bian Que was not a doctor at first, but only an innkeeper.
It is said that Bian Que once went out, saw an old man who was about to freeze to death, and immediately carried the old man into the room, and the old man actually survived after entering the treatment, but he did not expect that this old man was actually the famous divine doctor Sang Jun at that time, and later Chang Sang Jun passed on the medical secrets he had accumulated for many years to Bian Que.
A few years later, Bian Que also became a very famous doctor. Once, Bian Que passed through the Kingdom of Yu, and it happened that the crown prince of the Kingdom of Yu had just died. Bian Que and his party went to the gate of the palace of Yu Guo, and after asking a Zhongshuzi who liked medical skills about the illness of Prince Ming, Bian Que said to Zhongshuzi, if you go to repay the monarch, you will say that the prince is not really dead, and I have a way to bring him back to life. Hearing this, the monarch of the State of Yu hurriedly welcomed Bian Que and his party into the palace.
After Bian Que examined the prince's corpse, he said that the prince's illness was a corpse fern, mainly due to the prince's yin and yang imbalance and blood vessel blockage, which led to disorderly qi pulses and loss of consciousness, which caused the prince to suspend death. After seeking the consent of the monarch, Bian Que and his disciples began to treat the prince with acupuncture therapy, and prescribed several prescriptions to the prince.
After drinking the medicine, the prince was actually resurrected, and after knowing this, the whole country was extremely shocked, and he was also full of praise for Bian Que's medical skills.
Since then, Bian Que has become a real divine doctor in the hearts of the world, and the custom of the first seven has also arisen, the purpose is to prevent people from suspended death, and in the seven days after the fake death, timely find medical treatment to avoid the accidental killing of the person who is suspended.
