Because of the big gap between the ecological environment in the United States and Sichuan, Yaya is more likely to be acclimatized, and Xiangxiang belongs to Asia in Japan, so it can adapt quickly even if it is acclimatized.

Xiangxiang is the sweet baby of thousands of Japanese people in Japan. She eats fresh bamboo and lives better than any of us. Yaya's experience in America is a bit distressing. Yaya, who lives in America, suffers from extensive skin diseases, malnutrition, diarrhea and so on. Judging from the photos, Ya Ya is skinny and covered in dirt. Her eyes are not as good as before, but she is lonely and desperate.
