Under the joint care of experts from Sichuan and Ocean Park Hong Kong, the two pandas had undergone simulation training every day while in Sichuan, including preparing for the transport process and the conditions they will face when they arrive in Hong Kong.

"The two pandas are currently in good condition," said Cheng Yanxi, the vet with the China Conservation and Research Center for the Giant Panda who accompanied the two pandas on Thursday.

Cheng expected to work in Hong Kong for two to three months to help the pandas fully adapt to the new environment.

To understand the new pandas' characteristics, food preferences and behavior, Ocean Park Hong Kong sent a keeper to Sichuan in July to let the pandas get used to his voice, scent and presence, and the keeper also carried out some basic care training.
