The generation gap is inevitable. After all, the development between a few years is still very rapid. There is a generation gap, and it is normal to have different views on the same thing, but I don't think this should make us attack each other. When watching street interviews, I feel that many post-90s people are somewhat malicious and their words are offensive. Originally, the present society is a harmonious but different state, so there are different views on the same aspect.
The difference between post-90 s and post-00 s actually exists in many aspects. For example, after 90, most of them have entered the work, while after 00, many are still in school; Most people born after 1990 are full of work to make money, but after tears, they are still in a stage of longing for love. They want to talk about a sweet love more than making money, but after 90, they are numb to love. They just want to work hard and earn enough money. Although the difference between post-90s and post-00s sounds like many years, in fact, in many cases, the difference between post-90s and post-00s can't be seen from the outside, because many post-90s will deliberately dress up in a younger direction, and many post-00s will dress themselves more mature, which is also a status quo. Many post-90s are still in a state of staying up late and being excited, but many post-90s have already entered the health care stage early.
Of course, the generation gap only exists between people with different ages, but there is still no generation gap between people born in 1999 and 2000. People born in 1999 are likely to meet some post-00 s at school. These are all normal things. I met many post-00 s in college, but I didn't feel a big generation gap, because their birth dates were only a few months apart from mine.
