1, refinement. Thinning is to cut off branches that do not meet the needs of modeling from the base. By cutting off unnecessary branches, one can achieve the purpose of modeling, and the other can ensure good ventilation and light transmission, so that nutrients can be supplied to the reserved branches, so that plants can flourish and flowers can flourish. Watch carefully before thinning, especially for beginners, and don't cut it easily, because improper thinning will be difficult to make up. Thinning should not be done near the trunk, and the base of 0.5 ~ 1 cm should be reserved according to the branch thickness, so that the trunk is uneven and looks old and vigorous like a knot in one's heart.

2, short scissors. Short cutting is to cut off some branches and keep some according to the requirements of modeling, so as to stimulate the buds of the retained branches to form side branches. Cutting is also an important measure to shape and maintain the tree shape. It can make the taller trees shorter, keep the lower tree shape and make the branches thicker, thus making the tree bonsai more vigorous and magnificent.

3. Store branches and cut them. Keeping branches and cutting off stems is a unique modeling method carefully created by Lingnan bonsai artists according to Lingnan painting techniques, observing and imitating the modeling of ancient trees in nature. The specific method is: when the young trees used as bonsai grow to a certain thickness, they will be pruned vigorously and keep a few branches at appropriate positions and angles. It is best to leave branches of different lengths. If the remaining branches are called primary branches, then the side branches that grow on them are called secondary branches. When the second branch grows to a certain thickness, keep one or two branches and cut them short to promote the third branch. Prune in turn, year after year, cut dry and save branches. Then, after proper modeling, it becomes a big tree bonsai with thick bottom and fine top, lush foliage, vigor and simplicity, and beautiful shape.
