Information about the Thai Flag

The Thai flag 🇹🇭 has 5 horizontal stripes. The top and bottom stripes are colored red, the inner top and bottom stripes are colored white, and the middle stripe is blue.

Did you know, the flag used to have an Elephant 🐘 in it? The elephant was removed from the flag due to the king noticing the difficulty people had ordering the flag from other countries and also the flag was sometimes positioned upside (with the elephant upside down).
