Ask Qing Ning

Su Wen has been a classmate of Chen Yu for three years, but has never met her brother Chen Ning. Through Chen Yu's description, she had already imagined an image of a big brother in society. Later, when they met, Chen Ning said to her: "I also want to know the answer to your confusing question, why don't we discuss it together?" Later, after a quick question, I found out that Chen Yu was playing a big game of chess - the two brothers were indeed siblings!
