Pudong's Shanghai Wild Animal Park will stay open at night — until 9pm — from August 8, allowing visitors to explore the magic and glamour of the animal world after sunset. Many wild animals are active during the night as they sleep in the day, and visitors only get to see nocturnal creatures and some fierce animals in a state of slumber in daytime, the park operator said. "The night zoo will display another side of the lives of various wild creatures," said Zhong Yi, deputy general manager of the park.
