Are Zhuang people grouped under Dai people?

As far as I am aware, there is no 'Zhuang' in wegene as a seperate group, due to the difficulty of seperating them from the Dais( They are both Tai–Kadai) or the Hans(Due to the mixture).
There are many Zhuangs or Guangxi Hans who have done wegene test and I remember them being the most south and west among Chinese populations(something like 50% Southern Han and 50% SEA - I am pulling numbers out of my vague memory). Wegene groups almost all officially recognized ethnicities in China under 'Chinese/Zhonghua Minzu' category including Ughurs, Mogolians etc, so you should look into the subgroup breakdowns and take the 'Chinese' percentage with a grain of salt, especially if you are southeast asian - southern Chinese are very southeast asian genetically and obviously wegene will tend to put most of them under Chinese category.
I remember wegene staff has explained this once, but I can't figure out how to search for discussions at the moment...
现在要怎么搜索讨论啊？为什么我只能搜报告或者搜人

Thanks. I guess it’s not that easy to separate northern Vietnamese and southern Chinese dna. Until there’s more information available scientifically, I’m content with Zhuang being a part of who I am. 

If in this case, I would recommend you to analyze the result via other professional database(dnaland, 23andmr,etc).

This is just a small company based in Shenzhen rather than an advanced institution, you can’t fully believe in their results cuz there are plenty mistakes reported.

First you should make sure they are PURE Zhuang people, or you will be probably claimed Chinese (Han) ancestry. Then Dai is Thai-Chinese, they speak same language just different accents/dialects. P.s. since your fr

First you should make sure they are PURE Zhuang people, or you will be probably claimed Chinese (Han) ancestry. Then Dai is Thai-Chinese, they speak same language just different accents/dialects. P.s. since your paternal side is from China, I highly recommended you to test your father/grandfather’s DNA, they are very likely Han people (Hoa, Sán Dìu, Ngái in Vetnam are Han).

Thank you all for the answers. 
I had mostly southern Chinese, then Dai, and a little bit of other gashan, Hmong, and only ~6% Kinh (Vietnamese), no Korean, Japanese or Mongolian.
I had my test on 23andme first and the results only showed I’m 40.6% Chinese and ~50% Southeast Asian without breaking it down into smaller groups.  My father and my grandpa had passed away, so I’m trying to find out about my roots as I didn’t really listen and contain what my grandpa had told me. 
I’m not sure if they were pure Zhuang, I visited Guangxi when I was 15 and many people would come up and speak Chinese to me so I guess I didn’t look too different from everyone else. 

Some of the answers are Chinese people but not Han people, you should have your own judgment.

Come and get a WeGene report, it's worth it.
