Female number two in Snow Leopard and The Strong Years of Snow Leopard. Zhou Weiguo's second lover, female number two, Fan Xiaoyu's cousin and best friend Rola Chen (she was engaged in intelligence work under the pseudonym of Li Xia at that time). Zhou and Xiao's parents got married for them, but they loved each other, so he refused to get married and went to Huangpu Military Academy and changed his name to. Later, because Chen Yi and Zhang Chu got married (for work leave), Xiao Ya went to Nanjing to find Zhou Weiguo and worked in Nanjing No.4 Middle School for Girls. Later, she persuaded her to give up getting married after graduation (it turned out that they were first-time classmates, but going to Huangpu was purely Zhou's personal ambition). However, I never got married, because I didn't delay my graduation and study in Germany. After returning home, Zhou Weiguo immediately went to the battlefields of Songhu and participated in the Nanjing Defence War. After the war, Zhou Weiguo, Xu Hu and Fang Shengli went to the girls' middle school to find her. The devil has caught Xiao Ya, and Zhou Weiguo wants to save her, but because the machine gun shooting in front can only be behind the bunker, Xu Hu suddenly asks Zhou Weiguo to evacuate (because the Japanese outside are attracted). Xiao Ya knew that if he dragged on, Zhou Weiguo would be in danger, so he told him to leave and shot himself. Zhou Weiguo was devastated by her death. Anxious for revenge, Zhou Weiguo joined the bandits and the Eighth Route Army (because he thought any armed force could resist Japan) and killed the devils more bravely.

Losing Xiao Ya made Zhou Weiguo irritable, and after her death, she was obsessed with her. Many times when I think of her, Zhou Weiguo will burst into tears. After winning the race with Yang Dali, Zhou Weiguo shouted Xiao Ya's name on the mountain. Later, I grabbed a Browning pistol, remembered her, and was angry with Rola Chen because Rola Chen touched the pistol.
