No more joining. On July 6, 2020, Hohhot brothers and sisters stopped joining because the expansion speed was too fast and the store management could not keep up, which led to the decline of brand reputation. In order to upgrade the brand and adjust the joining policy, the brother and sister stopped joining. Brother and sister potato powder is located in Victoria Wanyue City, Daxue East Road, Saihan District, Hohhot, Inner Mongolia Autonomous Region.
