Salut Naimbs
His chinese name was Zhu Binhau and he was known as Etienne Tsu in France.
There is a short bio by Christophe Cony in Avions n°54.
He gets his civil brevet on march 6 1914.
He was a quite a good fighter : 3 confirmed victories and 6 probables between january 1916 and february 1917 (then he left frontline).
There is a web link about the Zhu/Tsu family made by a relative. Very interesting on the familial background : chinese catholic (since 17th century!) from Shanghai.
