Is there a bus from Litang to Hengzhou Town, Hengxian County at 6: 30 pm?

No, it used to be 5: 30 at the latest, and then several classes were cancelled. Now it seems to be 5: 00 at the latest.

At 6: 30, you can go to LULU and Gan Tang by bus. Then transfer from these two places to Zhu Ling or Shitang. There are many buses from Zhu Zero and Shitang to Hengzhou Town, but there are vans from Zhu Ling to Hengzhou Town, and there is no shuttle bus. The price is around 8 yuan. There is another car in Zhu Ling at 8: 30 at the latest.

If you really can't catch the bus, you have to stay in Litang. There are many hotels in Litang. The hotel is average and the price is not very expensive. 10 yuan can even stay for one night.
