The Olympic Games have a long history. The ancient Olympic Games can be traced back to 776 BC. The modern Olympic Games were held in 1896 and have been held every four years since then. It was not until 1920 that the International Olympic Committee flag was first used - the Olympic five-ring flag, which is the Olympic symbol that everyone is familiar with today.
The seemingly simple continuous ring made of five rings is not as easy to transform into a Luban lock structure and assemble.
