During WW 2 there was a Chinese area in Downtown Dallas. They were always catching grief because they looked Asian.

Finally they started putting signs in their windows saying 'We are Chinese' and advising customers that they were fighting Japan just like the US.

The entire area is gone now and was replaced with the skyscraper you see on the TV show 'Dallas', the building with the X on the sides that is supposed to be where JR has his office.
