What are the principles for shaping and pruning young jujube trees?

Shaping and pruning of young trees should follow the principle of light pruning and retaining more auxiliary nurturing branches, so that the branches of the tree during its young stage have as many leaves and twigs as possible for photosynthesis, promoting development and achieving the goal of early fruiting and high yield as soon as possible. In terms of pruning, summer pruning is the main approach, with winter pruning as a supplement, combining winter and summer pruning.
