An Lushan, favored by Xuanzong, rose up against the Tang Dynasty in Fanyang. An Lushan was originally a semi-final of a conference in Rongzhou, and later joined the army. Because of his bravery in the battle, he was promoted and reused by his adoptive parents john young and Zhang Shougui. An Lushan is cunning by nature and good at flattery. Seeing that Yang Guifei's brothers were deeply loved by Xuanzong, he tried his best to curry favor with Yang Guifei and shamelessly became her adopted son. An Lushan is a fat man with a big belly. Xuanzong once pointed to his stomach and joked, "What's in it? So big? " An Lushan quickly flattered: "There is only one heart loyal to the emperor in my stomach." Every time An Lushan appeared in front of Xuanzong, if Yang Guifei was present, he should worship the imperial concubine first and then the emperor. Xuanzong was very strange and asked him why. An Lushan said, "This is the custom of our conference semifinals. We worship our mother first and then our father. "
