[Xie Su has a younger brother who is two years younger than him.
In his sophomore year of high school, his younger brother said he wanted to get into the same university as him and then they would rent a house off campus together.
When his younger brother was in his senior year of high school, he was excited to find a good house, but his younger brother said he wanted to go to university abroad. When he asked why, his brother said that the major he wanted to study at a foreign university was more academic. This reason was far-fetched, and Xie Su couldn't accept it.
