Why is Wuwei Huangtai Building abandoned?

The national highway has been diverted and does not pass in front of the building. The Huangtai Building, built in 1995, was 21 stories high and was the tallest building in the Hexi area at that time. However, due to the diversion of National Highway 212, it did not pass in front of the building. The Huangtai Building, which was intended to be a hotel, became an unfinished building with no interior decoration. Huangtai Winery also gradually declined after its glory.
