In history, Thailand was once called "Siam". Thais sometimes call Thailand "Meng Tai". In Thai, "Meng" means "country", and "Thai" means "freedom". Therefore, in the eyes of Thais, Thailand is a "free country." In addition, in the world, Thailand is also called "the country of smiles", "the country of Buddhism", "the yellow-robed Buddha country", and "the country of elephants".
