In ancient times, Xi'an was the favorite place of emperors and emperors of all dynasties. After many dynasties, it was a city with a strong sense of history. The city wall of Xi'an is also an indispensable scenic spot worth visiting. If you want to climb the city building, you need to climb from the South gate. Tickets are inexpensive, just in time for the Lantern festival, but a look at the Lantern festival, really a big failure, looks too ugly. Because of the lamp festival, the rental points that used to ride on the city walls have been changed a lot. If you have time, rent a bicycle for a ride, but be prepared. If you ride a circle at normal speed, it will take about two hours. A friend with poor physical strength can do it. The city wall can give you a glimpse of the inner city and the outer city. It has a very obvious sense of the times. It is suggested that we go after 4 p.m., which is not hot, and we can see that Xi'an is more historic at dusk.
