And widely planted in Henan, Shanxi, Shaanxi, Gansu, Anhui and other places in China.

China's sweet cherries are mainly distributed in Shandong, Liaoning and other regions. Among the major cherry producing areas, the big cherries in Dalian, Liaoning Province and Yantai, Shandong Province ripen the earliest, because the greenhouse technology is widely used to grow cherries in these two areas, and the cherries planted in greenhouse technology ripen about 15 days earlier than those naturally planted outdoors.

There is a story on the Internet: A woman ate a cherry together with the stone, which caused a series of symptoms such as dizziness, headache, abdominal pain and difficulty breathing. She was rushed to the hospital for emergency treatment and was out of danger. What caused the woman to be poisoned was cyanide contained in the small cherry pit.
There is a substance called cyanoside in cherry pit. When eating by mistake, it will combine with gastric acid to generate cyanide ions, which will cause us dizziness, abdominal pain, disturbance of consciousness, nausea and other uncomfortable symptoms, which will be life-threatening in severe cases. The almonds and apple seeds we eat also contain such substances, so it is better to throw them away. When this harmful substance reaches a lethal dose, there is no time for rescue.
Cherry is delicious, so be careful of the red "bomb" on your mouth when you eat it.
