Extended data:
The battle between Zhu Yuanzhang and Chen Youliang Longwan refers to the battle between Zhu Yuanzhang and Chen Youliang in Longwan Town of Yingtianfu in 1360. In this campaign, Zhu Yuanzhang finally defeated Chen Youliang, and recovered many cities occupied by Chen Youliang in one fell swoop after this campaign, which was a turning point in the confrontation between Chen and Zhu.
After this war, Zhu Yuanzhang's power gradually overtook or even surpassed that of Chen Youliang, which changed Zhu Yuanzhang's passive situation and laid a solid foundation for Zhu Yuanzhang to defeat and kill Chen Youliang in the Poyang Lake War and destroy the Chen Han regime established by Chen Youliang.
