1. If an insurance company organizes a trip to Hong Kong and Macao, it is likely to take you to an insurance company in Hong Kong to visit and attend classes, and fool you into buying insurance in Hong Kong. This is not to say that insurance in Hong Kong is not good, but that many mainlanders who go to Hong Kong to buy insurance can't settle their claims. There are many differences between Hong Kong insurance and mainland insurance.
2. Check whether this activity is officially organized by the insurance company or the personal behavior of the sales department or salesman to prevent being cheated. If you want to check, call the official telephone number of the insurance company, usually 955XX, not a fixed telephone number.
3. It's not impossible to buy insurance in Hong Kong, but one thing, even if you go to Hong Kong, you should think twice after listening to the lecture, which is really good.
Remember to be greedy and cheap in Hong Kong.
