The Rio Olympic Games' organising committee is in the process of making new official flags for China, after some eagle-eyed viewers spotted errors in the old ones.

Complaints arose over flags which were raised during the medal ceremonies for Chinese athletes in swimming and shooting. The perspectives of the four small stars in relation to the one big star were slightly off. They all had two points at the base, and one at the apex, which is wrong, as you can see from the proper flag.

According to the organising committee, the defective flags were made by a Brazilian company and they're due to deliver a new batch of proper ones as soon as possible.
