In addition, major museums in Shanghai have generated more than 12,000 kinds of similar products, with sales volume hitting more than 49 million yuan last year, the website said.

"For museums, developing such products is also a way of supporting daily operations of museums and relieving the country's financial burdens," said Hou Ningbin, director of the Emperor Qinshihuang's Mausoleum Site Museum.
