The Palace Museum in Beijing unveiled a plan on Tuesday to control the number of visitors after dealing with overwhelming crowds for years.

According to Shan Jixiang, director of the museum, the draft plan sets an upper limit for daily visitors at 80,000. The proposal is awaiting approval from various authorities that have jurisdiction.

"It's a must, because our museum is too crowded during peak season," Shan said. "We have to be responsible for visitors' safety."
