Zhuge Liang's cemetery is located in Dingjun Mountain. Who can introduce the geomantic omen of this cemetery?

"Biography of the Three Kingdoms and Zhuge Liang" records: "Liang died in the army at the age of 54. ..... Bright commandment buried Hanzhong Dingjun Mountain, because the mountain is a grave ... ". There is no dispute about Zhuge Liang's cemetery in Dingjun Mountain. Why did Zhuge choose Dingjun Mountain as his graveyard? I think there are three reasons:

First, when Liu Bei and Cao Cao competed for Hanzhong, the battle of Dingjun Mountain ended with the comprehensive victory of veteran Huang Zhong's knife over Xia and Liu Bei Group. From then on, Hanzhong belonged to Liu Bei, and Liu Bei also successfully called it "King of Hanzhong". Dingjun Mountain is of extraordinary significance to Zhuge Liang's Han Shu Group.

Second, when Zhuge Liang stationed troops in Hanzhong to attack Wei, he used Dingjun Mountain as a camp for a long time, practicing martial arts to recuperate, and had deep feelings for Dingjun Mountain.

Third, Zhuge Liang is proficient in astronomy and geography, and he is quite familiar with Feng Shui. Looking up, I saw nine loess beams around Dingjun Mountain heading straight for Zhuge Cemetery like nine Huanglongs. "Kowloon Birthday" is an auspicious omen in geomantic omen. Why didn't Zhuge choose the tomb here?

Note: "Jiulong" is distributed in Yuanping Village, Zhuge Village, Wujiawan Village and Gaomiao Village around Dingjun Mountain, and can be clearly seen on the surrounding mountains at an altitude of1000 m.
