As we all know, grabbing red packets on line won popularity with the people during the Spring Festival in 2015. From then on, more and more people have been crazy about it. However, people's attitudes towards the topic vary from person to person. Personally, there's no doubt that not only does it bring people happiness, but also send blessings to people in a special form. Also, it's obvious that it is more convenient. However, as a saying goes, each coin has two sides. It is not an exception, it also has some bad effects. If people can't grab the red packets, people may feel sad or ill-tempered ,even break their cellphones. What's worse, it may lead to the crime. Once people are trapped in cheat, their qq number, telephone number and bank acount code will become a castle in the air. Facing these phenomena, as far as I am concerned, on the one hand, the government should take steps to protect people from being cheated in red packet trap. On the other hand ,people should raise the net safety awareness. Rememberto look before you leap. In addition, keep in good emotion no matter whether you can grab red packets.
