Why didn't Zhuge Liang go to guard the street pavilion himself?

Zhuge Liang's Northern Expedition was to attack Wei, not to guard street pavilions. As a head coach, he deployed in battlefield centers around the country, focusing on three attack points (main attack and feint attack): Qishan, Longxi and Shangguan. Ma Su was also a general with many original ideas at that time, and he was one of the key training objects of Zhuge Liang, so he was very suitable to be a guard in a street pavilion. However, Zhang He led the main army to fight back, which he did not expect.

Zhuge Liang (181-23410-8), a native of Yang Du, Xuzhou (now yinan county, Linyi City, Shandong Province), was an outstanding politician, strategist, essayist and calligrapher during the Three Kingdoms period. When he was alive, he was named Hou of Wuxiang. After his death, he pursued loyalty to the marquis of Wuxiang. Because of its military ability, the Eastern Jin regime was posthumously named King Wu Xing. Representative prose works include An Example and A Book of Commandments. He once invented the wooden ox, the flying horse, the Kongming lantern and so on, and transformed the crossbow, called Zhuge Lian crossbow, which can hit all targets with one crossbow. In the twelfth year (234), Yu Jianxing died in Wuzhangyuan (now Qishan, Baoji).

Liu Chan regarded him as a loyal minister, so later generations often referred to Zhuge Liang as a loyal minister and Zhuge Wuhou. Zhuge Liang is the representative of loyal ministers and wise men in China traditional culture. He devoted himself to his life and died.
