I want to know the answer to the following question:
The Mahayana teachings were first propagated into China by who?
All the background I'm provided with is that "Some scholars have traditionally considered the earliest Mahāyāna sūtras to include the very first versions of the Prajñāpāramitā series, along with texts concerning Akṣobhya Buddha, which were probably composed in the 1st century BCE in the south of India.[note 40]". Is that enough to answer the question?
Answer: no
