Chicken hair letter is a special type of mail created by the military and civilians in North China during the Anti Japanese War. For official documents and letters that require rapid transmission, use chicken feathers as a symbol to make the sender and receiver aware of their urgency and importance. One match is the fire speed, two matches are ten thousand urgent, and three matches are ten thousand urgent. The number of matches determines the speed and machine density. After 1940, the Japanese imposed economic blockades and embargoes on the base areas, and without matches, they switched to using chicken feathers, which led to the creation of the Chicken Feather Letter.
