Hello. The "separated core" of walnuts is called "huangren" by professionals. It refers to the phenomenon that after walnuts are played with or picked from the tree for too long, the water in the walnut slowly dries out, resulting in "the pulp is separated from the core". This is a normal phenomenon, and you don't need to care too much about whether the other one is separated from the core. , just continue to play with it, do not let it separate from the core artificially, otherwise it will cause damage to your love core. Wait for the other one to leave the core.
