秦朝时期，大秦军队已经征服了百越民族聚居的部落，算是把他们纳入了秦朝的版图之内，当时还在那里设立了三郡，那时的越南算是中国的一个边陲省级地区。后来的两千年中，分分合合，越南地区脱离了中原王朝自己独立建国了，不过由于地域不大，兵力不强，再加上抱大腿心态，所以一直都是我国的藩属国。在美版知乎Quora上，美国网友提问道：越南人认为他们的祖先是中国人吗？这个问题引起各国网友的围观和热议，我们看看他们的观点。

Hahaha, this is a controversial topic. After all, it is about politics, genetics and culture.
哈哈哈哈，这是一个会引起争论的话题，毕竟这关乎政治、基因和文化。
1. The first thing we need to understand is that there are differences between people in the south and north of Vietnam. This can be seen from their appearance that southerners are darker and northerners are whiter. There are also significant differences in facial features and appearance.
1、 我们首先需要了解的是，越南南部和北部的人之间存在差异。这一点可以从他们的外表看出，南方人更黑，北方人更白。面部特征和长相也有显著差异。
The people in northern Vietnam are very similar to those in Guangdong and Guangxi, and the people in southern Vietnam are very similar to those in Malaysia and Cambodia.
越南北部的人与中国广东和广西的人非常相似，南越人与马来西亚人和柬埔寨人非常相似。
2. Vietnam and China have a history of close interaction and exchange, which has been recorded for thousands of years. According to records, many people from southern China migrated to Vietnam and settled and lived here.
