Camellia oleifera is not a small rape. Rape is called green vegetable. It is an annual or biennial herb of Cruciferae and Brassica. Youmaicai, on the other hand, is oily and fragrant lettuce, belonging to the genus Lettuce in Compositae, and its original species is produced in the Mediterranean coast.

Youmai cuisine has different names in different places. It is called "Youmai" in North China, "Yumai" in Northwest China and "Zhongmai" in Northeast China.

The biggest difference between rape and rape is the length. The short dark green is rape, and the long light green is rape. In taste, oily wheat is better than rape, and it tastes crisp, like lettuce leaves or even lettuce, but rape doesn't.

In our daily life, we can buy rape and look at the color. Rape with green color and yellow leaves is the representative of fresh rape. If you buy rapeseed that has been sprinkled with water, you'd better eat it as soon as possible at this time, otherwise it will go bad easily.

We'd better choose rapeseed with big leaves and roots, because these rapeseed are more delicious and taste better than vegetables with long roots and small leaves.

Be sure to clean the bought oil wheat vegetables, prepare a pot of water, and then put baking soda in it for a while, so that the vegetables will become clean.
