Before the end of Qing Dynasty, Taiping area was mostly swamps and meadows. Majiagou River flows from southwest to northeast, and Ashe River meanders into Songhua River from the east and west sides of this area. On both sides of these two rivers, there are dense wicker bushes everywhere.
On the south bank of the river (now the former site of Hasu No.5 Factory), a yellow sand hill is naturally formed, which looks like an earth dragon lying across the earth from west to east. On this mound, there are three elms, each three inches thick.
These three trees stand on three legs at close range and look like three umbrella covers from a distance, which is very spectacular. /kloc-in 0/744, the Lu family of Han people settled here, and then three or four families came here to open up wasteland, gradually forming a small village, so people took these three old elms as the name of this village-Sanshutun.
1923, the Liu family built a small brick kiln near Sanshu. Due to a lot of sand digging, three old elms gradually exposed their roots. 1929, three old elms were blown down by strong winds. At that time, no one dared to move, for fear of destroying the feng shui in this area. It is said that these three old elms grow on dragons and are the embodiment of "God".
1932, the Japanese invaders began to build railway stations in this area, and named Sanshu Railway Station after Sanshu. Since then, the names of Sanshu have become famous all over the country. After the founding of People's Republic of China (PRC), the people's government of Taiping District named a main street across the region as Sanshu Street. So far, the name uncle has a history of more than 240 years.
