始因羅什法師得名。先是長安自漢廢到秦興三百餘年。朝市曠絕。雖數伽藍歸向者少。姚興世鳩摩羅什（此云童壽）。於大寺中搆一堂。以草苫蓋於中譯經因此名之也。

This first gained its name from Master Kumārajīva. Previously, from the Han abandonment of Chang'an until the rise of the Qin, more than three hundred years had passed, and the court and marketplace were desolate. Although there were several saṅghārāmas, few people took refuge in them. In the era of Yao Xing, Kumārajīva (translated as 'Youth of Long Life') constructed a hall in the Great Monastery and thatched it with straw, within which he translated sūtras; hence it was named after this.
