1 янв 909 г. - Moveable type printing
Описание:
Invented the first moveable type printing method. Developed around 1040AD during the Song Dynasty. Time Consuming and expensive as it required a clay carved book for each individual letter and symbol and a single error could ruin an entire sentence. However, the books became faster to print and were hardened by fire so they could be re-used in other places.
