First of all, I want to tell you that there are two Gaobeidian in China and one Gaobeidian in Beijing. The Baigou wholesale market you mentioned is Baigou Town, Gaobeidian, Baoding, Hebei Province, but now Baigou is independent and does not belong to the jurisdiction of Gaobeidian. When you arrive in Beijing, you can take the 9 17 bus to Zhuozhou, then take the bus to Gaobeidian, then take the bus to Baigou, and then take the bus to Baigou and 8 yuan. You can also take a taxi to Baigou, and the price is generally not higher than that in 60 yuan (during the day). You can sit at Gaobeidian Railway Station all the way to downtown. Generally from Zhuozhou, they usually get off at the railway station. Of course, you can't find 9 17 in Beijing. You can also take a long-distance bus to Liuliqiao or Mukuangyuan, which takes a long time, about three hours. There is a direct bus to Gaobeidian.
