Tickets for a place depend on where you want to go. If you want to save money, it won't cost much. After all, students can go to botanical gardens, science and technology museums, city god temples and other places. Basically, within 7 days, you may not need to spend 300 yuan. If you want to go to the Oriental Pearl and Jinjiang Paradise, you may need to prepare more credit cards.
