What kind of transportation is the cheapest from Zunyi to Hengshui, Hebei?

According to the most economical terms, go to Guiyang first, and then take the train from Guiyang to Hengshui (36 hours), it will only cost 300 yuan, and I will give you another plan. I think the cost performance is relatively high, and fly directly to Shijiazhuang in Zunyi (600 to get it, sometimes cheaper than Guiyang), and then take the train from Shijiazhuang to Hengshui, only tens of yuan.

The only way to save money is to use hard seats on ordinary trains, first from Zunyi to Shijiazhuang, and then from Shijiazhuang to Hengshui.
