Flash card, a term that must be known after 1980s, was around (1990- 1998) that year. Whenever there are good-looking cartoons or best-selling cartoons (mostly from Japan), a commodity will be derived. Toys will print cartoon characters on the size of a card. The card is divided into two layers, the front is attached, the back is paper, and the front is attached. Let the pattern shine in the light. This kind of flash card will be sold in the egg twister. You can twist one for one yuan, but some styles are scarce, and the probability of being twisted is quite low. If we had a scarce product at that time, it would be particularly awesome. Merchants will also raise the price of this scarce flash card, ranging from 2- 100 yuan, and some styles even cost hundreds of yuan. Almost all our children have it. At that time, the most popular cartoons were dragon ball, beautiful girl warrior, slam dunk master, saint, the history of the Three Kingdoms, street fighter and so on. Flash cards are our memories of the post-80s generation, and I have saved more than 100.
