Go out of the East Gate of Renmin University, go north along Zhongguancun Street, pass through Tsinghua West Gate and Yuanmingyuan, cross the North Fifth Ring Road and reach Shangdi Island. After arriving at the roundabout, turn east, go straight to Xiaoying roundabout, turn north at Xiaoying roundabout, go north along the auxiliary road of Badaling Expressway, and go straight along the auxiliary road of Badaling Expressway to Badaling. After arriving at Badaling, try to go around the back of the mountain and enter Badaling Scenic Area from the back of the mountain.

The above routes, ways and methods can ensure that the landlord will not spend a penny to visit the Badaling Great Wall. The journey is about 65 kilometers, so it is estimated that the landlord can definitely walk in two days. If the landlord wants to stay on the road, he'd better bring a tent and sleeping bag. Ha ha.

If the landlord wants to spend some money to save time and effort, he can take bus No.355 at the East Gate of Renmin University, get off at Xisanqi, transfer to Express 9 19 and get off at Badaling. It will take about 2-3 hours. Save about 13 hours and one night accommodation than walking. After arriving at Badaling, it takes about half a day to buy a ticket (it seems to be 45 yuan/person) to enter the scenic spot, compared with going around the back hill. After the tour, take the bus back the same way.

It takes 12 hour to go back and forth on the same day, plus the tour time, but it costs about 70 yuan.

It takes about 85 hours to go back and forth on foot and sightseeing time, which is a good exercise for both will and physical strength, and can also save money around 70 yuan (I wonder if the money saved is enough to eat, drink and sleep for 85 hours, hehe).

The above is a joke, chat with everyone and laugh at the landlord. Who told you to say, "You'd better go in for free"? Hehe, but the way to take the bus is right.

What city does the landlord mean to go to? The concept of Beijing is very big, both traditional and present.
