Bamboo is an evergreen plant belonging to the grass family, which has an underground stem (commonly known as bamboo whip) that grows underground. The underground stem is horizontal, slightly hollow in the center, and the same as the bamboo above ground with nodes, and nodes and dense, in the nodes on the growth of many fibrous roots and buds. Some buds develop into bamboo shoots or bamboo seeds, while others do not grow out of the ground, but only grow horizontally in the soil and develop into new bamboo whips, which are called "whip bamboo shoots" when they are still young and are dug up and eaten. In the fall and winter, the buds grow in the soil and are covered with bamboo shoot shells, which are extracted as "winter bamboo shoots".

The buds on the underground stem nodes will grow upwards out of the ground in the spring when the weather warms up, and they are covered with bamboo shoot shells, which we call "spring bamboo shoots". It is also very delicious to eat, and can be made into dried bamboo shoots, salt bamboo shoots, yucca chips and canned food shipped around. However, at this time of the year, the soil is still relatively dry and there is not enough water, so the spring bamboo shoots do not grow fast, and some of the shoots remain in the soil for the time being, as if the arrows are on the string and have not yet been shot out. If there is a thorough rain, the soil moisture, the spring shoots as if the arrow was shot out of the same, have jumped out of the soil.

As soon as the bamboo shoots come out of the ground, they grow very fast. If you want to dig up extra bamboo shoots for food, you have to do it before it's too late; if you dig it up late, the bamboo shoots will grow into bamboo.
