The reasons why this vegetable is not called cucumber are as follows:

Cucumber is called "cucumber" instead of "cucumber" because the cucumber people eat is immature. When the fruit of cucumber is ripe, its skin will change from green to yellow. Therefore, according to the color of the fruit, the immature cucumber is called "cucumber" instead of "cucumber". In fact, the skin of mature cucumber is yellow and the inside is yellow. In the market, people often buy immature cucumbers, because they are crisp and moist, suitable for raw or cold. Mature cucumber is more suitable for cooking or soup.
