Wei Lan and Wei's twin sisters are said to be of mixed blood of China, Korea and the Philippines. How do they get along? Please elaborate on their family background.

As far as I know, Wei Lan and Wei's mother is Korean, and their father is of mixed blood between China and the Philippines. Both sisters were born in Hong Kong, but they were separated from each other since childhood. Wei Lan went to Korea with his mother, and Wei stayed in Hongkong with his father. Wei Lan lived in South Korea for five years. At the age of ten, his mother went to work in Japan, so she returned to her father's arms in Wei Lan, South Korea. Wei Lan's father is a singer. After discovering the singing talents of the two sisters, he began to teach them to sing consciously until he met Dawn and Lei Songde.
