Which dynasty in China lost Viet Nam?

Vietnam was defeated by China in the Ming Dynasty. Just after Judy captured Vietnam, Vietnam did not want to become a part of the Ming Dynasty, because Vietnam had formed its own independent nation and culture, so the resistance movement continued. In order to quell the rebellion, the Ming Dynasty invested a lot of troops and money every year. In the eyes of the Ming Dynasty, Vietnam was a burden. At that time, it was not wrong for Zhu Zhanji to give up Vietnam. He made this decision out of the current environment and his own political views.

The history of Vietnam

In the Yuan Dynasty, the large-scale attack on Annan also failed. During the civil strife in Annan, the Ming Dynasty invaded Annan and set up a Chief Secretary for a time, but it only lasted for about 20 years and then hastily withdrew. The Qing Dynasty also launched a war against Annan, which also ended in failure. From the Song Dynasty to the Qing Dynasty, Vietnam existed as a vassal state, at least nominally belonging to the Central Kingdom. But in modern times, influenced by the western national independence thought, Vietnam did not want to become a vassal state.
