However, his reign only lasted a few months before he died of illness.
His first and only son, whose name was either never recorded or never given at all, was born at the time of his death, so Pugen's mother, Lady Qi, installed him as the new Prince of Dai.

The people of Dai thus chose his cousin, Tuoba Yulü, to succeed him.
[2] Likely due to their very short reigns, he and his father were never posthumously honoured during the Northern Wei period.
