With a daily budget of just several hundred yuan, tourists in Shanghai have about a 10 percent chance of staying in a hotel room with subpar hygiene.

Fifty-four budget hotels in Shanghai out of 500 inspected have been penalized for poor hygiene, the city's Health Supervision Department said.

The department recently released the results of inspections of more than 500 economy hotels in the first quarter. among them were branches of many well-known chains, such as Hanting Inns and Hotels, 7 Days Inn, Home Inn and GreenTree Inns.
