The intersection between South side Chicago resident and semiconductor expert is vanishingly small. Those who grow up in a disaffected part of the US and go on to study EE or CS do so through a US college opportunity which will funnel them into a US semiconductor job where they will be treated better than the treatment dark skinned people get in China. It’s common for restaurants in major Chinese cities to have “No Black” signs in their windows as a “COVID measure”, for example. https://www.hrw.org/news/2020/05/05/china-covid-19-discrimin...

The probability of that happening is not so big considering people from such areas tend to have low quality schools around them, which tends to mean low test scores, maybe even involvement with the "justice" system, no real opportunity to land a semiconductor job.

What you said sounds nice, but I doubt happens much in practice.

The linked article has no pictures of the sign.

I have friends living in Shenzhen, I asked them, and they said they never saw such signs. It could be that they are visiting different groups of restaurants or hotels etc.

If you had bothered to read the article, not only would you have seen the linked image and video[1], you'd have also read the tomes of evidence that goes against your anecdote.
