I went in September, and Nanjing was still very hot. The zoo wasn't too crowded. The "animal-centered" philosophy is deeply rooted in people's hearts. There are almost no animal shows here. The zoo's slogan is "The zoo is the animals' home, and we are visiting the animals' home." Therefore, the entire park is designed with animal welfare in mind. The enrichment program is excellent: what you'll see at Red Hill isn't animals lounging in bare concrete, but rather climbing, foraging, and playing in environments that simulate natural ecosystems. For example, Bear Valley has waterfalls and streams, Monkey Mountain has a complex rope system, and keepers hide food throughout for the animals to "treasure hunt." Because the environment is comfortable and stress-free, the animals generally appear more relaxed and happier, exhibiting more natural behaviors. Wear comfortable shoes! Wear comfortable shoes! Wear comfortable shoes! The animals are usually more active in the morning, and there are relatively fewer people. Be patient and observant: Don't rush. Spend more time in each enclosure, observe carefully, and you might discover cute little animals hiding in corners or witness their interesting behaviors. Make good use of the facilities: There are sightseeing vehicles and rental strollers available if you're feeling tired. Understand and support its philosophy: Visit with a heart that respects life and observes nature; the experience will be doubled.
