  The introduction (p. 2) says that not many Buddhist monks in medieval East Asia necessarily read Sanskrit fluently, and the Conclusion (p. 28) says Sanskrit study was not widely taken up in China. These passages support the general point that Sanskrit literacy was limited, but they do not establish that only a handful of Chinese could read it at any given time or address their ability to compose in it.
