"Tamtựkinh", The Three Character Classic, Trimetric Classic or San Zi Jing (traditional Chinese: 三字經; simplified Chinese: 三字经) is one of the Chinese classic texts. It was probably written in the 13th century and attributed to Wang Yinglin (王應麟 Vương Ứng-Lân, 1223-1296) during the Song Dynasty (Đời Tống). It is also attributed to Ou Shizi (區適子 Âu Thích-Tử, 1234-1324).

For those who knows Chinese you will see that this is a very clever and witty translation of a short segment of ancient Chinese teachings ever done by a foreigner !!!
