Four giant pandas have already attracted 140,000 tourists in their first month after arrival at Qinghai-Tibet Plateau Wild Zoo in Xining, capital of northwest China's Qinghai Province.
The four much-treasured animals came to the zoo's Panda House from Chengdu Research Base of Giant Panda Breeding in Sichuan Province.
Qinghai plans to launch a series of education activities about pandas in the coming three years.
