The shortest river in my country is only 90 meters long

As the industrial structure changes, the role of rivers in cities has also changed. There is such a place hidden in China. It is the shortest river in my country, with a length of only 90 meters. It cannot be found on the map, but its name is well-known to every household! Curious friends may ask, where is the shortest river in my country? What different scenery are there? With these questions and curiosity, let’s talk with you today about things about Rehe. Rehe is located in the Chengde Summer Resort in Chengde City, Hebei Province. It is named after the hot springs in the resort. This river does not freeze even in the cold winter, and even emits white steam, so it is called "Hot River". The birthplace of Rehe is a high-temperature mountain spring in the northeast corner of Chengde Summer Resort, with abundant water. It flows through the Chenghu Lake, Ruyi Lake, Upper Lake and Lower Lake of the Summer Resort, and finally merges into the adjacent Wulie River. Rehe is only 90 meters long and cannot be found on the map. Its uniqueness lies in its year-round constant-temperature spring water, which can remain at around 8 degrees Celsius even in severe winters. This rare natural phenomenon makes Rehe a highlight of the summer resort.
