2. Due to the great influence of the Tang Dynasty on overseas, by the Song Dynasty, "Tang" had already become a synonym for China in the southeast overseas countries. During the Song, Yuan and Ming Dynasties, foreign countries called China or something related to China "Tang". Not only the Tang Dynasty was regarded as the land of China, but also China people were called Tang people. China people have a deep historical complex. The Tang Dynasty was a powerful dynasty in the history of China. Overseas Chinese often call themselves "Tangren", and the place where they live together is conveniently called "Chinatown". Chinatown was originally named "Datang Street". 1673, Nalan Xingde wrote a miscellaneous note on the Green Water Pavilion: "In Japan, people began to go in the Tang Dynasty, and the residents called it' Datang Street', which is ten miles long today." 1875, Zhang Deyi called Chinatown "Tang Dynasty City" in Travel Notes Around Europe and America, which was called Chinatown in English. The history of Chinatown is centuries earlier than the English name Chinatown, so foreigners call all the cultures in China surnamed tang, so Manchu-style fashion is also called "Tang suit".
