This bosom friend, Bian Xiaozhen's husband, Xue Zhuren, was born in 194 1. He is an airborne soldier. He was organized and trained to be an army leader. Later, he was sent to the university to study English. While studying English, he chose another foreign language-Swahili. Xue Zhuren's task is to give lectures to Tanzanian Air Force pilots. At that time, the commander of Tanzania's air force was named Luohan Port, and Xue Zhuren was ordered to give them lessons. Just after class, Commander Luohangang immediately stood up from his seat and gave a military salute to Xue Zhuren. At that time, he made a decision and said, "Xue Zhuren speaks very well, and he will be invited to teach our pilots in the future."
