Introduction to Chengdu Road: Chengdu Road, formerly known as London Road, belongs to the British Concession in Tianjin and was built in 1929. This area was originally a swamp. In conjunction with the dredging project of the Haihe River, the British Concession Industry Bureau reclaimed it into a land suitable for urban construction in the 1920s. Since then, large residential areas have been built, attracting many dignitaries from the military, political, industrial and commercial circles in the early years of the Republic of China. .
