Is Xiao Siyuan an an only child?

Not an only child. Two years after Xiao Siyuan died, his mother sent her second son Xiao Rongji to join the army. Foreign troops openly violated the consensus reached with our army, openly crossed the border and provoked, and deliberately created conflicts in the Wan Jiale Valley. At that time, the head of the team, Qi, led only a few officers and men to negotiate sincerely with foreign troops and solve problems through negotiations. However, they were fiercely attacked by foreign troops. In the face of foreign troops several times that of our army, Qi and others were fearless, but after occupying favorable terrain, they fought to the death. In order to defend the territory of the motherland, the head of the regiment, Qi, was seriously injured in the fierce battle. Battalion commander Chen Hongjun, soldiers Xiao Siyuan, Chen Xiangrong and Wang Zhuoran died heroically. Xiao Siyuan, who was in charge of photography and evidence collection at that time, rushed into the combat team desperately. Originally, Xiao Siyuan had successfully broken through, but seeing that his comrades were besieged by foreign troops, Xiao Siyuan rushed forward again and struggled to rescue his comrades. Xiao Siyuan, if he succeeds or dies, protects his comrades from armed attacks such as stones and sticks. At the end of the battle, Xiao Siyuan died heroically at the age of 24.
