First of all, there are many frauds against the elderly, but they are mainly in two aspects. First, regarding the falsification of various nutritional products and drugs, the elderly generally have some health problems and are anxious about health problems. However, fraudsters generally take advantage of the psychology that the elderly usually pay attention to their health and expect better health, and sell various useless health care products and nutrients to the elderly for fraud. The product itself is useless and even harmful to people's health. Second, about all kinds of so-called high-tech household items, such as high-tech pillows, quilts or cups. Old people think that they can't keep up with the times, so they will choose to trust their high technology. At the same time, they will show their so-called high-tech functions to the elderly through various means, so that many elderly people can pay for those useless products and get many benefits.
Second, how should we improve the vigilance of the elderly? First of all, family members should tell the elderly some basic anti-fraud knowledge and common fraud routines, so that they can distinguish some simple fraud routines. Old people rarely use smart phones or modern devices, so they are easily out of touch with society and unable to understand those professional scams and the latest fraud methods. Therefore, they need their families to care more about them, tell them more tricks, and let them have a precaution. Secondly, the community can organize some anti-fraud lectures to systematically tell the elderly about anti-fraud knowledge, so that the elderly can be vigilant. The elderly generally lack specialized anti-fraud knowledge, so the community needs to organize such activities to improve their vigilance.
