The biennial Biennial Exhibition is still worth visiting as one of the world's three major art events. Two days of broken legs, even more can't be seen. Students can spend 15 euros for two days (although our teacher paid for the money so did not buy tickets), many exhibition halls do not have air conditioning, hot is just a word. But they are all artists who like them very much, so it's worth it. Buy a 24/48/72 hour day ticket, the price is very cheap for under 29 years old, as long as 22 euros for three days, just go shopping. (Drink two liters of water a day without taking the toilet)
