Explain how the three types of cliffs are defined.

Definition of cliff style in three cases:

1. The base of cliff stump bonsai is generally vertical, inclining from the lower part to one side, with the trunk downward and the adjacent tips upward, showing a trend of one-stop backward, giving people a vigorous sense of vitality.

Second, the cliff stump bonsai emphasizes root cultivation. Lifting the roots can not only show the state of the old trees, but also alleviate the dynamic trend of bonsai and produce visual balance. If only relying on root modeling can not meet the balance requirements of bonsai, stones can be used to achieve the goal.

Third, the basin of cliff stump bonsai should be medium and deep, and it should be placed on several high tripods.
