This vegetable is coriander that looks like celery, but it is shorter than celery. But many people don't know that coriander is just one of its many common names, and its scientific name is coriander.
Yán sui is the scientific name of coriander. It is also called coriander and Xiangsui, and it is also called Yanxi and Yansi in some places in Guangdong. Coriander's hometown is in the distant Mediterranean area of Europe. It was a vegetable seed brought back from the western regions by Zhang Qian of the Western Han Dynasty in the first century BC, and then it was planted in China. Cantonese in Guangdong is one of the most complete dialects preserved since the Qin Dynasty, so it is also called "Yanxi" and "Salt Silk" directly in the local area, and its pronunciation is very similar to that of "Coriander".
