The lease of American giant panda Ya Ya has officially expired and she has been handed over to the Chinese Memphis Zoo. The Memphis Zoo held a Chinese exhibition recently to celebrate 20 years of cooperation with the Chinese Zoological Association and to wish Ya Ya a safe journey. After returning to China, Ya Ya will have to undergo quarantine in Shanghai to ensure she is free of any unknown diseases or germs. The quarantine period is set at 30 days. Ya Ya came to the US in 2003 and started her career at the Memphis Zoo with her partner Lele. Lele passed away in February 2023.
