Title:
Sanskrit

Context:
Sanskrit has also influenced Sino-Tibetan languages through the spread of Buddhist texts in translation. Buddhism was spread to China by Mahayana missionaries sent by Ashoka, mostly through translations of Buddhist Hybrid Sanskrit. Many terms were transliterated directly and added to the Chinese vocabulary. Chinese words like 剎那 chànà (Devanagari: क्षण kṣaṇa 'instantaneous period') were borrowed from Sanskrit. Many Sanskrit texts survive only in Tibetan collections of commentaries to the Buddhist teachings, the Tengyur.

Question:
Who sent missionaries to China?

Ashoka
