How to get to Xilinhot by car from Hailar, and how to reverse on the way? thank you

Hailar-Tongliao-Xilinhot

Now the bus from Hailar to Tongliao seems to be cancelled (specifically ask the passenger station), so it is a bit troublesome to take the bus to Xilinhot (Hailar-Ulanhot-Tongliao-Xilinhot)!

You can take a train from Hailar to Tongliao!

There are three trains from Tongliao to Xilinhot every day, which are: 05: 30, 10, 10, 15: 50!
