2.141

In the dingwei year of Northern Wei, Empress Dowager Feng returned the governance, and the Sovereign of Wei began to attend to state affairs personally. He changed the reign era and was diligent in governance; rewards and punishments were strict and clear, promoting pure integrity and demoting the corrupt, so that the Northern Wei realm was praised for its good governance. At the Northern Terrace of Chang'an, he erected Yongning Monastery, with a seven-tiered stūpa thirty zhang high. Furthermore, at Tiangong Monastery, he made a Buddha statue forty-three chi tall, using seventy thousand jin of bronze and six hundred jin of yellow gold (Imperial Annals of the History of the Northern Dynasties).
