Where did people travel in the 1970s, 1980s and 1990s?

I am engaged in tourism. In fact, I know that people have traveled to Sanya now. The international tourist island is not the biggest attraction, but its beautiful seascape makes people yearn for it. But if you have the ability, going abroad is also good, but I still think China is good. I also want to go abroad. I will go abroad after visiting Chinese mainland. Hehe, the trip to Hainan will make you remember it for a lifetime. Because of the infection here, I chose to settle in Hainan. I just want to give you my own ideas.
