Excuse me! After weight map for cloth, directly save or support save as? Thanks.

Either should work - if you save as an asset then every scene that loads that asset will get the weight map, if you just save the scene then only that scene will have it. Which you do will depend on whether this is a change made specifically for one scene, that would not work in most other scene, or is a change you want available every time you use the piece of clothing.

Thanks cat.
