(1) The natural grain of Sakyamuni Bodhi should be preserved. When polishing, use sandpaper to follow the surface of Sakyamuni Bodhi fruit.

2. The black spots on the surface of Sakyamuni fruit should be cleaned up, otherwise it will not look good after playing for a while. More importantly, pay attention to the connection of the lines when cleaning up the black spots. Never break the good lines in order to clean up the black spots, causing the lines to hang in the air "lonely".

3. Don't destroy the bud eyes of Sakyamuni. The thousand eyes with intact bud eyes are the best Sakyamuni bodhi, followed by the thousand eyes inlaid with beeswax.

3. That is, change 800 mesh sandpaper to polish the pattern clearly.

4. Replace 1200 mesh sandpaper to smooth the surface.
