Zhuge's three brothers' parents died young, and Zhu Gejin, the eldest brother, took on the responsibility of raising his younger brothers and sisters. Zhu Gejin was only 15 years old that year. Zhu Gejin is very clever and eager to learn. He went to Luoyang to give lectures in his early years and became famous at the end of the Eastern Han Dynasty. Later, when Cao Cao attacked Luoyang, Zhu Gejin went to Jiangdong to escape the war. Jiangdong Sun-style Group attached great importance to Zhu Gejin's talent and appointed him as an official. Zhu Gejin became loyal to Sun Shi. After the establishment of Wu Dong, Zhu Gejin was the general of Wu Dong, and his son Zhuge Ke became the trustee of Sun Quan.
In order to meet the famous teacher, Zhuge Liang, the second brother, went to Jingzhou to worship Pang Degong as a teacher and learn the strategy of governing the country and keeping the country safe. After learning, he devoted himself to Nanyang, ready to choose his own master. At this time, Liu Bei was thirsty for wisdom and asked Zhuge Liang to come out of the mountain. Zhuge Liang was moved by Liu Bei's sincerity, so he began a magnificent life dedicated to Liu Bei and later Shu Han.
Zhuge Dan, the third brother, is not the brother of Zhuge Liang and Zhu Gejin, but their brother. Zhuge Dan has been staying in Xuzhou Langya. He doesn't travel around like Zhuge Liang and Zhu Gejin. Xuzhou was later returned to Cao Wei, and Zhuge Dan naturally became Cao Wei. The Zhuge family of Langya is a big family in Xuzhou. After Cao Pi proclaimed himself emperor, in order to stabilize Xuzhou's aristocratic family, he invited Zhuge Dan to hold an official position. In this way, Zhuge Dan also embarked on the road of official career in Cao Wei.
