Intermittent amnesia mainly refers to a certain period of time when it is easier to forget things, sometimes good and sometimes bad. Amnesia, on the other hand, is one of the manifestations of always being prone to forgetting things, and is closely related to emotions. There are four types of amnesia as follows: 1. Local amnesia: the individual completely loses memory of what happened in the hours before and after certain traumatic events 2. Selective amnesia: the individual selectively remembers some of what happened in a certain period of time and forgets some 3. Total amnesia: the individual completely forgets the background of his or her life, including name, address, etc. 4. Continuous amnesia: the individual forgets the past experiences since a certain year In ancient times, amnesia was called “Myriad Pens”, which means remembering what happened a long time ago, but not what just happened. For example, a person can clearly tell the birth of a child many years ago, but cannot tell what color socks he or she wore or what he or she had for dinner. Rong Haisan in the TV series “Chinese Husbands” found out that he had Mythopoeia. Usually people do not realize that it is a disease and it is difficult to cure.
