Non-touch equipment has recently been applied in Hangzhou Grand Theater for gate control in a bid to prevent the spread of the new coronavirus.

Three ticket checkers are standing at the main entrance of the Opera Hall. Showing the e-ticket QR code instead of having a paper ticket scanned, you can pass through the gate in less than one minute.  

That is to say, audiences can walk into the theater in an orderly manner when it resumes operation.
