The tip of the tongue is a little forked. What happened?

Eat more vegetables and so on. Lack of cellulose may also be related to calcium deficiency. I also had this situation in junior high school, which should be more serious. There are still cracks on the tongue coating. Later, because my father likes to teach himself Chinese medicine and other things, he began to pay attention to his eating and rest habits. Now he is much better ... I wonder if it is the same as yours. If you are not at ease, you can go to the hospital for a check-up ~
