This may be incredible, mainly because the division of Texas is limited. There are three counties in Hebei (Wuqiao, Jingxian and Gucheng) close to Decheng District, and most of their development zones or factories and enterprises are close to Dezhou. Some people are born and raised in Texas and work in Texas, but their hukou is in Hebei. So there are only 55w people in statistics, which should be very different in reality.
