One of the leaders of Shennong tribe who invented fire was called Emperor Yan. People don't have enough to eat, so he studies agriculture. Later, he taught everyone to grow crops so that the big family could have enough to eat. Shennong saw everyone's health problems again, so Shennong tried a hundred herbs to treat everyone. A person got a disease during the treatment, and the medicine for this disease is only available on the cliff. If this medicine can't be eaten, this person may die of illness, so Shennong climbed the ladder to collect medicine on the shelf and saved this person. Since then, this place with Shennongjia has been called Shennongjia.
Shennong tasted a hundred herbs. It is said that "tea" was discovered by him and also has the function of detoxification. Every time he feels toxic after trying herbs, he immediately eats some tea to detoxify. Until Shennong tasted a deadly grass "heartbroken grass", it was too late to detoxify it with tea. Shennong, the first great man in history, devoted himself to medicine and human health!
The leader of the ancient Jiang tribe in China was honored as Shennong, Kuikui, Lianshan, Lieshan and Zhu Xiang. Legend has it that the leader of this tribe is called Jiang. Because he knows how to use fire to get the throne, he is called Emperor Yan.
