The Palace Museum in Beijing will cap the number of daily visitors allowed through the gates beginning on June 13.

Museum director Shan Jixiang says the upper limit for daily visitors will be set at 80,000 to help alleviate the problem of overwhelming crowds during the peak tourist season.

Personal identification cards will also be needed to purchase entry tickets to discourage scalpers, and all group visitors need to book tickets online in advance.

The museum received more than 15 million visitors in 2014 with numbers exceeding 80,000 people on 42 days of the year.
