My girlfriend went to Dalian to work, and sent me a text message just a few days after she went there, telling me that many people get up at five in the morning and sleep in a kang. ...

Are you sure it's called Yangcheng Photo Frame Factory? There is no registration information of this name in Dalian industrial and commercial registration Information. But if it is a factory, it is estimated that it is not a pyramid scheme. There are indeed many factories that have internal regulations that prohibit carrying and using mobile phones. However, judging from the name of the factory, Yangcheng is a regional name, and general enterprise registration information should not be named after other cities or regions unless approved by the local government. So you'd better know more details. If not, you can call the police for help. But at least get the basic information of the factory. If her mobile phone can access WeChat, let her use the positioning function of WeChat to send you her current location, which is much more convenient.
