The background of Lily's trip to South Korea is the establishment of diplomatic relations between China and South Korea. Lily was only 2 years old when she went to Korea. When I came back, it was the Asian financial crisis in 1998, and South Korea could not afford to return the goods.

Lily and Mingming were not taken good care of in Korea, and their malnutrition was very serious. It took them a long time to recover from their return to China.
