Four giant pandas met the public in southwest China's Sichuan Province, as the Jiuzhaigou panda park officially opened on Tuesday.

Located at an average altitude of 2,380 meters in Jiuzhaigou County, Aba Tibetan and Qiang Autonomous Prefecture, the park covers an area of around 3,220 square meters and is a base for the protection, research and publicity of giant pandas.

The four pandas, Xin Xin, Tian Tian, Hai Hai and Xiao Liwu, came from two bases under the China Conservation and Research Center for the Giant Panda, all located in the same province, on Oct. 31, 2019.

Of them, Xiao Liwu was born in San Diego of the United States in 2012 and returned to Sichuan in May last year.

The China Conservation and Research Center announced an in-depth cooperation with Jiuzhaigou panda park in the breeding and training of giant pandas on Tuesday, making the park as a special base in Jiuzhaigou County.

"For the conservation, we will unfold our research in training giant pandas with survival skills in a selected natural environment and develop new modes to prepare them for release back into the wild afterwards," said Li Desheng, an expert with China Conservation and Research Center for the Giant Panda.

The Jiuzhaigou panda park receives a daily maximum of 2,000 tourists only from Sichuan Province currently due to the COVID-19 pandemic. Tourists with tickets booked online will need to show their ID cards and health codes at the checking point.

According to the latest national wild panda survey published in 2015, there are 31 wild giant pandas in Jiuzhaigou County.
