Ong Schan Tchow (Chinese: 翁占秋; pinyin: Wēng Zhàn Qiū; Jyutping: Jung1 Zim3 Cau1; Pe̍h-ōe-jī: Ang Chiàm-chhiu) (also known as Yung Chan Tchow, Ong Chan Chiew or Ang Chan Chiew in the Hokkien dialect) alias Yung Len Kwui (Chinese: 翁联桂; pinyin: Wēng Lián Guì; Jyutping: Jung1 Lyun4 Gwai3; Pe̍h-ōe-jī: Ang Liân-kùi) (also known as Ong Lien Kuei) (19 September 1900 – 20 December 1945) was born in the ethnically Hokkien city in the eastern part of Longyan prefecture, Southern Fujian Province, China.

In Paris, Ong studied at École Nationale Supérieure des Beaux-Arts, the National School of Fine Arts of the École des Beaux-Arts where he learned to combine Western art techniques and perspectives with traditional Chinese painting techniques.

In addition, he obtained a Master of Arts in Law, French and Political Science from the University of Paris where he also enrolled for his Doctorate.

It was during his time in Nanjing that Ong produced one of his monumental works – a compilation of paintings of Chrysanthemums with accompanying poems and commentary from well known persons.

All the exhibitions were solely for the War Relief Fund in aid of the civilian victims in China, Malaysia and Singapore.

Ong was creative in his combination of techniques of East and West from a realism and attention to detail to an expressive free style.
