On May 20, in the panda park of the China Conservation and Research Center for Giant Pandas at Wolong, Sichuan, the pandas huddled together in fear. In the past, there were piles of bamboo and shoots here, but now there is not a trace. A panda tried to grab some ornamental bamboo outside the cage to eat, while another panda actually grabbed a handful of grass and stuffed it into its mouth. Due to the lack of bamboo, apples and other food, the pandas had to learn to drink porridge with the help of the staff.
