Only by understanding the subconscious can you clear the subconscious. There are too many things in the subconscious, and the content is too wide. Because we don't realize that this person is subconscious, it is almost impossible to clean it up. Only in one or several things, when we know that the subconscious mind is at work, we may explore it in various ways, and then change it through changes in our own thinking and actions.
