In September 1975, the Chinese government gave the Mexican government a pair of giant pandas as presents -“Ying Ying” and “Bei Bei”. It was the first time for Mexico to have a panda of its own.
Thanks to the efforts of the Chapultepec Zoo in the capital – Mexico City, Mexico ’s first generation of giant pandas, “Ying Ying” and “Bei Bei”, gave birth to 7 panda babies, becoming the panda couples with the strongest ability to breed abroad in more than 40 years .
At present, “Shuang Shuang” and “Xin Xin” are still alive. They are are the second and third generations of “Ying Ying” and “Bei Bei”.
These two old pandas are both female, named Shuang Shuang and Xin Xin. Since their birth, they have lived in the Chapultepec Zoo in Mexico. Shuang Shuang has turned 30 years old this year and Xinxin is 28 years old. It’s equivalent to 100 years of age of a human being.
In Mexico, cactus is definitely a gourmet. Due to the geographical environment of Mexico, there are rich cactus plants and edible cacti have also been developed. The locals love the cactus food. And they eat it too. In Mexico, when people hand food to pandas, they also include cactus in it. Xin Xin and Shuang Shuang consume a lot of cacti every day.
The reason for this is that there are too few bamboos in Mexico, which are not enough for pandas’ daily consumption, especially when Xin Xin’s brothers and sisters are still alive. There were just not enough bamboos for all the pandas. Therefore, the breeders gave them some cacti tentatively, and it turned out that they really liked eating it. They could also digest it well. According to the research of experts, we found that cactus and bamboo are more nutritious for pandas. Therefore, cactus has become a standard meal for pandas.
In 1984, pandas were officially listed as an endangered species. According to the international conventions at the time, no animals could be used as gifts. They could only be applied for renting by the host country. Since Ying Ying, Bei Bei and their descendants had been given to Mexico before 1975, they’re naturally not within the scope of the Convention. In turn, the descendants of Ying Ying and Bei Bei no longer belonged to China, Shuang Shuang and Xin Xin become the only two living pandas that do not belong to China.
