About the Flag
"In the local Thai language, the flag is known as Thong Trairong, which translates to the Tricolor flag.
The National Flag of Thailand features five horizontal bands of red (top), white, blue (double width), white, and red. The red color symbolizes the nation and the blood of life. The white color represents the religion of Buddhism and the purity of the Buddhist faith. The blue color stands for the monarchy." (source: worldatlas)
