Extended information:
It is said that after Jiang Taigong helped the King of Zhou gain the kingdom, in order to thank the gods for their help, he gave them fiefdoms.
Of course They are all famous mountains and rivers, but Mount Tai is not among these fiefdoms. It turns out that he found that Mount Tai has good feng shui and is suitable for cultivation, and he wants to use Mount Tai as a place for his retirement in the future.
Later, Huang Feihu found Jiang Taigong and wanted Mount Tai as a fiefdom. When Jiang Taigong was thinking about it, an immortal or a female general came. After a closer look, it turned out to be Huang Feihu's sister Huang. Concubine, she also asked that Mount Tai be given to her as a fiefdom.
Jiang Taigong thought: Now, brother and sister both want to live in the same place, and maybe they are too embarrassed to fight over it. In that case, Mount Taishan will still be mine. So he said, "There is only one Mount Tai, and only one of you brothers and sisters can be there. Which one of you wants to be on Mount Tai?"
But neither of them would let him. Jiang Taigong said, "Why don't you compete to climb Mount Tai? Whoever gets to the top first will get Mount Tai, but magic is not allowed." The brother and sister nodded in agreement.
After the competition started, Huang Feihu ran as fast as he was flying to the top of the mountain, while Huang Fei slowly climbed the mountain while looking at the scenery. When Concubine Huang reached the top of the mountain, her brother immediately ran over and said, "Sister, if you lose, don't compete with me for the top spot."
"Who said I lost? I got there earlier than you. I didn't see you when I arrived, so I thought something had happened to you, so I went down to look for you again! I want to prove that I arrived earlier than you, but I can't show you the proof until the prime minister arrives!"
Mr. Jiang! After arriving, she understood the situation and asked Huang Fei to provide evidence. Huang Fei walked to the highest stone and dug out an embroidered shoe from the soil.
In the end, Jiang Taigong could only give Mount Tai to Huang Concubine, and Huang Concubine became the deity on Mount Tai, and is now the Grandma of Mount Tai!. What happened? It turned out that Huang Fei used magic during the mountain climbing and placed her embroidered shoes among the rocks on the top of the mountain, but no one else noticed.
Huang Feihu was always reluctant to leave Mount Tai, and finally did good deeds at the foot of Mount Tai. The people nearby respected him as the God of Mount Tai and built a temple for him - Dai Temple.
