Tongxingming lu 同姓名錄

Tongxingming lu 同姓名錄 "Persons with identical names" is an encyclopaedia written during the Ming period 明 (1368-1644) by Yu Yin 余寅 (1519-1595), courtesy name Junfang 君房 or Senggao 僧杲, style Hancheng 漢城, from Yinxian 鄞縣, Zhejiang. He also wrote the books Nong zhangren ji 農丈人集, Yiwei xinzhi 乙未新志 and Huanyou liji 宦遊歷紀.

The book imitates the Liang-period 梁 (502-557) book Gujin tongxingming lu 古今同姓名錄 and serves as a kind of supplement, including identical personal names from ancient times to the Yuan period 元 (1279-1368). The book of 12 juan length was only preserved in fragments quoted in the encyclopaedia Yongle dadian 永樂大典. The original size was 4 juan, but Yu Yin later added 8 further fascicles. Zhou Yingbin 周應賓 (1556-1626) compiled a supplement (Lubu 錄補) of 1 fascicle. Yu Yin's supplement also includes many identical geographical names and designations of animals. The whole book lists more than 1,600 identical names of 2,700 persons.

The oldest surviving print dates from 1617. The Tongxingming lu is included in the series Siku quanshu 四庫全書.

There is another book of the same title and a length of 8 juan written during the Qing period 清 (1644-1911) by Wang Tingcan 王廷燦 (early 18th cent.). It served as an addendum to Yu Yin's book and continues the list of names until the end of the Ming period. Wang Tingcan's book also quotes from the two precursor books: juan 3 and 5 are literal quotations from the Gujin tongxingming lu and the Tongxingming lu.
