Why can Anhui's freight volume rank first?

I'm from Huainan, Anhui province, and there are endless trucks on provincial and national highways, which may be related to Anhui's geographical position of connecting the east with the west and connecting the north with the south! In recent years, it has undertaken the transfer of enterprises in the Yangtze River Delta, and the high industrial growth in the province has also played a role in pushing up the freight volume. As a late-developing province, the first freight volume is really commendable. Come on!
