How to get to Mutianyu Great Wall is more convenient?

Last time I went to Mutianyu Great Wall, I chose the bus through train from Heping Xiqiao subway station. Tell me about the process:

I placed an order the day before departure, and soon received a phone call from the tour guide telling me the departure time the next day.

The next day, I arrived at the subway station 15 minutes in advance. I thought I needed to wait for a bus or a tour guide, but I didn't expect to see a tour guide after I came out. This must be awesome!

The tour guide counted the tickets in the car and sent them directly to us after arriving at the scenic spot.

When I came back, I got off early, so I read a book in the bus rest area and blew the air conditioner for a while. Very comfortable

At about 4:30, get off at Heping Xiqiao subway station, and the trip to the Great Wall is over.
