Bell and Drum Tower Square, the most prosperous and lively place in Xi'an, is close to the Hui people. Due to the impact of the epidemic, there are not many people now, and now the Bell Tower and Drum Tower are free of tickets until May 31, 2020, but an appointment is required. This time to travel in Xi'an is very cost-effective, most attractions are free of tickets, I recommend everyone to travel to Xi'an.
