What Zuo An said during the day was partly correct and partly incorrect. I have lived (studied and worked) in Cuba for three and a half years and know all aspects of Cuba very well.
The average monthly salary of Cubans is about 100 yuan. You can talk to foreigners, go to sea, surf the Internet (as long as you have money, but few people have money to surf the Internet), and it is even more fake to have a computer in prison. But it is true that lobsters are not allowed to be eaten privately, because lobsters are one of the main sources of foreign exchange in the country and are not allowed to be caught privately. But you can eat in a restaurant. There are four TV stations in Cuba now, but the TV is not issued by the state, so you have to buy it yourself. Hotels and embassies have satellite TV, and you can receive three channels from China CCTV.
Cuba not only accepts students, but now some universities also welcome China students, because it can bring them foreign exchange (tuition) income. Now there are more than 400 China people in Cuba (old people, embassy staff, overseas students, China companies, etc.).
The left bank probably didn't stay in Cuba for a long time during the day, and the news he heard was not accurate. I have many Cuban friends, and now there are two Cuban students studying Chinese in China.
