A scientist says that the gate was created in the fourth century, while the Forbidden City's pamphlet says that it was built in 1651. Both of these are incorrect: the gate was built in 1417, although it was rebuilt in 1651 after being burned down. The scientist also says that the reigning emperor, the Yongle Emperor, was the one who built the gate. While he ordered its construction, it was designed by Kuai Xiang in conjunction with other architects.
It is stated on several occasions that only the Emperor could pass through the Gate of Heavenly Peace, when it was actually the Gate of China that had this restriction.

It also does not list Eritrea, which split from Ethiopia.
