Which emperor of the Persian empire is the wild donkey emperor talking about?

After Sasandi Bacheland V ascended the throne, he fought with Dongluo for two years, and it was basically a draw. During and after the war, Bachland handed over the power of internal affairs to Mir-Narsieh, an old minister of the former dynasty, and made a gesture of following the general plan of the late Yazdegerd III dynasty. As for buckland himself, he devoted all his energy to pleasure, completely ignoring the growing invasion. On the one hand, buckland is particularly keen on music and poetry. He recruited thousands of musicians, singers and poets from India, where he could sing and dance, entertain himself in Sassanian Empire and make big cities like Taixi Peak sing and dance all day.

On the other hand, Wang Zhongwang is very keen on hunting. In Sassanian dynasty, hunting was an entertainment or sport that almost every emperor was keen on. Lions (Iranian lions), wild boar, various deer and wild donkeys are common prey. Buckland's favorite prey is the Central Asian wild donkey (Onager), which is widely distributed in the vast arid grassland and Gobi between the Mediterranean and Daxinganling Mountains. Wild donkeys have two characteristics, and they are very good at long-distance running and group activities. Although their absolute speed is not outstanding, chasing wild donkeys is definitely a job that requires patience, organization, wisdom and strength. So in order to shoot wild donkeys, buckland often travels in groups with all the guards. Buckland is very good at archery. On one occasion, he was hunting with Mendel, King of Lechmi, and saw a lion pouncing on a wild donkey. He immediately shot an arrow and killed the lion and the wild donkey.

With the expansion of hunting scale, buckland expanded his own guard, and the time spent on each hunting became longer and longer. The subjects soon got tired of the emperor who was keen on pleasure and hunting but neglected the affairs of state. Because of the emperor's special hobby, his subjects gave him an ugly nickname-Gur, Gor, which means wild donkey in Persian, so Bahran V was also called bahram Gore or wild donkey Bahran.
