Then, he went to Paris and often went to Julian Painting Academy. However, this kind of formal education can't affect him. So, he went to Wikis, Switzerland to meditate alone. There he met Klee (1909). 19 12 visited Kandinsky in Munich and participated in the famous exhibition Young Knight. The following year, he went to Berlin and attended the first autumn salon with the main painters of expressionism. Prior to this, Walden, the organizer of the salon, had published a strange sketch of Apu in his The Knockout magazine-characters drawn with changeable lines. 1944, Apu returned to Paris and met Marcos, Jacob, Franco franco modigliani, Apollinaire and Delaunay.

In the meantime, he met Sophie Daobe, who later married him, and was influenced by her stronger art. They cut straight lines with a paper cutter and made a big sticker (19 18).
