Video raises hotel hygiene concerns

More travelers have been bringing along their own sheets, sleeping bags, kettles and bathrobes after a video posted online raised public concern about the hygienic condition of hotel rooms.

Lanmei Test, an organization that claims to be independent, released a video on WeChat of a recent undercover inspection during which its employees left marks on sheets, toilets and cups at several five-star hotels.

The marks - visible only under ultraviolet light - were still there when Lanmei employees checked into the same rooms the next day.
