Time-preferably during the day
Location-it should be in a crowded place, a department store or a restaurant, teahouse or coffee shop with good business. If you know where the camera is best, choose a place where the camera can see clearly.
Communication-The mobile phone must be turned on and charged for emergencies.
Precautions-In order to prevent any abnormality, who to see (give as much real information as possible, such as mobile phone number, not just the screen name), and when it is best to tell family members or trusted girlfriends, so that they can call you at 1 hour after the appointed meeting time. For example, when she asks whether to eat glutinous rice balls or jiaozi at night, "glutinous rice balls" means safety, and "jiaozi" means that if your family or friends can't get through to your mobile phone, there must be something wrong.
Remember, safety comes first!
