The movable type was invented during the Northern Song Dynasty, which is 1041-1048 AD. In the video, it has been said that the movable type was invented around 1045-1058 AD.
Instead of the simplified Chinese”中国” shows in the animation when introducing the movable types, these two characters should be in traditional Chinese “中國” and should also be horizontally flipped for printing.
The video says that Chinese people invented the paper 2000 years ago. In fact, however, papermaking skills had been improved by Cai Lun in Eastern Han Dynasty, which is around 105 AD. In historical records, long before Cai Lun, there are also some records about the paper.
The video claims that papyrus was invented in 4000 BC which actually appeared around 3000 BC.
Good catch!
interesting points. it would be better to include the citation or evidence for those points.
