This is an inevitable phenomenon in developing society. We took the route of Taiwan Province Province 20 years ago. When the post-80s people grow up to be over 40, they will become an open society. It will be like Taiwan Province Province now. Sex culture will be open. Our next generation will also change because of my way of education. It's not surprising to be topless in America now. There are several women in the graduation notes of American universities, naked all over the sky. Exposing pictures and yellow messages everywhere can't reach that nature, but this day will come soon. Cohabitation is inevitable. It's definitely not accidental. Sexual maturity is gradually becoming juvenile. For parents now, they are busy with work and have little discipline for their children. This is also a fact.
