Based on the available information, here’s a suggested itinerary:
7th: Head to High-Speed South Railway Station (高铁南站) at 11:00 am.
8th: Visit the zoo after getting off from the railway station. This should take up most of your day and give you plenty of time to explore and enjoy the animals.
Leave any further plans or appointments until a later date, as it seems like you have enough on your plate for today (9号 played with).
Feel free to adjust this schedule according to personal preferences, but hopefully, this gives you an idea of how to prioritize your day!
