Yes. There was a nice Chinese movie about the battle at the lake Changjin.Is that right?
CHINESE FORCES FORCE AN AMERICAN RETREAT
In November 1950, about five months after the Korean War began, as the U.N. forces under Gen Douglas MacArthur approached the Yalu River at the Chinese-North Korean border, China warned that it would not tolerate a unification of the peninsula under U.S.-U.N. auspices. After several weeks of threats and infiltrations, China’s People's Liberation Army entered North Korea the en masse in later November, launching viscous attacks, forcing MacArthur into a costly chaotic, retreat down the peninsula.

In November 1950, 300,000 Chinese soldiers attacked American forces along the Chongchon Yalu and Rivers. Again Americans were caught disastrously unprepared. After a fierce battle at the Changjin (Chosin) Reservoir, they were pushed southwards as South Korean forces had been pushed before towards Pusan during the previous summer.
Really epic. As for me, one of the best war movies made in recent years
