In "how do you look so good", Wu Xin recalled the quarrel with Du Haitao. Two poor children fought in a foreign land. Once they quarreled on the bus. Later, they made up because they didn't want to spend 4 yuan more. Do you admire the immortal friendship of 4 yuan.
Haitao later said, 'there's nothing 4 that can't be solved with a dollar.' sister Xin just replied, 'you may have bullied me a lot when I was a child.'
