5.115

（三十　辛巳）　沙門朱士衡。於洛講道行般若經。義有闕文發足于闐求正本。漢地講經自此而始。

(30. Xinsi [261 CE]) The śramaṇa Zhu Shixing lectured on the Daoxing bore jing in Luoyang. Because the doctrine had lacunae in the text, he set out for Khotan to seek the authentic original. The lecturing on sūtras in the land of Han began from this.
