There are a few study related to San-Mao (1943-1991, Chen Ping, or Echo Chen), including master degree thesis、articles from journal and other publishers. Yet, they are in Chinese. 1979 was the year she lived in La Palma Island and on 30th of September Jose died. We hope the enclosing San Mao’s bibliography note might be of help though it’s also written in Chinese. We do not provide translation assistance to our readers. Thank you for your understanding, and good luck on your research.
