Bamianfeng 八面鋒

Bamianfeng 八面鋒 "The Eight-sided vanguard", also called Yongjia bamian feng 永嘉八面鋒, is an encylopaedia from the Southern Song period 南宋 (1127-1279) compiled by an unknown author. The preface, dating from the Hongzhi reign-period 弘治 (1488-1505), attributes authorship to a certain Master Yongjia 永嘉先生. Some sources wrongly believe Chen Fuliang 陳傅良 (1137-1203) to be the compiler.

The book of 13 juan length is divided into 88 organised according to a question-and-answer principle. It was probably compiled as a handbook for the preparation of the state examinations, as a loose collection without the intention to publish it as a book.

The Bamianfeng is included in the series Huhailou congshu 湖海樓叢書 and Siku quanshu 四庫全書. There is a print by Du Mu 都穆 (1459-1525) from the Ming period 明 (1368-1644).
