Large branch toward the lower part, wire the main trunk into an S-curve, large-tree style
Large branch longer than the middle part, straight-trunk large-tree style
Large S-curved trunk, short and powerful style
No special features, make the most of the situation, maximize strengths and avoid weaknesses, natural style
Ordinary curved-trunk material, just select and position the branches
Large branch growing toward the lower part, cascade is also an excellent choice
Small stump at the base, very beautiful as a parent-and-child style
Few branches on the lower part, welcoming-pine literati style is a good choice
Double-trunk brother style, the material needs to be grown out first, widen the angle between the two trunks
Make the leaning one even more curved, to rise first restrain first
U-shaped fork, double trunks avoid each other and form naturally
Contrast between curved and straight, tension and relaxation in balance
Three-trunk large-tree style, grow the middle branch thick first
