The so-called Xiaoyanglou is a garden villa in the old concession of Tianjin. The mansions in Tianjin appeared after the Opium War. Due to the invasion of foreign forces, foreigners began to establish their new colonies in Tianjin, so they began to build houses for themselves. The earliest foreign building was the foreign firm building in the British concession, and later the church of Wanghailou in the French concession appeared. Later, a religious incident occurred in Tianjin, and the insurgents burned the Wanghai Tower. The Qing government was incompetent. In addition to building a new Wanghai Building in the old site, it also suppressed the uprising people in Tianjin. In addition, the new watchtower is three feet taller than the old watchtower, and it is still a scenic spot in Tianjin today. With the gradual invasion of foreign capital, foreigners have also set up banks and foreign firms in Tianjin, and there are many foreign-style hotels, among which the famous ones are Gordon Hall, Youshunde Hotel, German Club, which used to be a German consulate, and later Kailuan Building, Zhonghui Hotel, Bohai Building and so on. At this point, Tianjin has become a city with many tall buildings.
