A new article by Ma Xuming 马旭明 on Jifei's 即非 Dharma Transmission Certificate given by Yinyuan 隐元 has been published in China. The original 1657 certificate and a few letters were published in 蜗庐藏珍図录 by 天六书房 in Japan (page 20). (Unfortunately, there is no such a book and publisher in American cataloging system.) These materials were not included in Yinyuan's complete collections.
The certificate is as follows and resembles the one Yinyuan received from Feiyin Tongrong 费隐通容: “从上承嗣来源 ：六祖下、南岳让、马祖一、百丈海、黄檗运、临济玄、兴化奖、南院颙、
风穴沼、首山念、汾阳昭、石霜圆、杨岐会、白云端、五祖演、圆悟勤、虎丘隆、天童华、密庵杰、
破庵先、无准范、雪巗钦、高峰妙、中峰本、千岩长、万峰蔚、宝藏持、东明山、海舟慈、宝峰瑄、
天奇瑞、绝学聪、月心宝、禹门传、天童悟、径山容，明历丁酉年寓普门福元禅寺老僧隐元琦手书付即
非一禅人。”
