Tadpoles become frogs. First, they grow two hind legs, and then two forelimbs. Slowly, the tail will shorten and gradually become frogs. Tadpoles live in water. When spring comes, groups of tadpoles always look for food against the current in the water. This symbolizes that tadpoles have the spirit to survive in adversity.

Frogs lay many eggs at a time. These eggs become tadpoles after 4 to 5 days. After about two months, tadpoles can develop into young frogs. About a month and a half later, the root of the tadpole's tail begins to expand, and a week later, the hind legs grow. Then the forelimbs begin to take shape, and the tail will shorten at the same time. At this time, the little tadpole will become a little frog.
