Is it easy to communicate when working in Vietnam?

Good communication. Working in Vietnam, easy to communicate. In northern Vietnam, especially in the provinces bordering China, some people can speak Chinese, and basic communication is ok. Vietnam is located in the south of China, clockwise, with Yunnan Province and Guangxi Zhuang Autonomous Region in China in the north, Nanhai in China in the east, Cambodia in the southwest and Laos in the west across the Changshan Mountains.
