泰国国旗，被称为“Trairanga”，意为“三色旗”。这面旗帜由三条水平的色带组成：上部是白色，中间是红色，下部是深蓝色。每种颜色都蕴含着深刻的意义，反映了泰国的历史、文化和价值观。

白色 represents purity and the religion of Buddhism, which is the predominant faith in Thailand. Red symbolizes the land and the blood of Thai people who have fought for their country's independence and unity. The deep blue, placed at the center, stands for the monarchy and the nation itself, representing Thailand’s strong ties to its royal family and national pride.

The design of the Thai flag has evolved over time. The first version was adopted in 1917 under King Vajiravudh (Rama VI). Initially, it had only two horizontal stripes: red on top and white below. Later, during World War I, the king added a central blue stripe to show solidarity with the Allied Powers, particularly France and Britain, which also had blue in their flags. Since then, the tricolor design has remained unchanged, becoming an enduring symbol of Thai identity.

The Thai flag is not just a national emblem but also holds significant cultural importance. It is flown proudly across the country, especially during important festivals and ceremonies. When displayed, it must be treated with respect; for instance, it should never touch the ground or be used as decoration after its purpose has been served. During the national anthem, Thais often pause and stand at attention as a sign of reverence.

In times of crisis or celebration, the Trairanga serves as a unifying force, reminding citizens of their shared heritage and commitment to the nation. Whether fluttering in the breeze atop government buildings or adorning private homes, the flag embodies the spirit of Thailand—a blend of tradition, resilience, and unity.
