[3] In 1913, when Oey Tjioe Yong, the former director of the popular Indies Chinese newspaper Sin Po stepped down, Hauw, who was already a major shareholder in the paper, was appointed in his place.
[7] In particular the paper harshly attacked Phoa Keng Hek and Khouw Kim An, high-profile Chinese Officers, and accused them of corruption and abuse of authority.
[8] In early 1919, Hauw became embroiled in a court case against J. R. Razoux Kühr, the former editor of Sin Po who was then at rival paper Perniagaan.
[10] In 1919 Sin Po sent him to China to negotiate with the government there about the matter of potential repudiation of that citizenship; when he tried to re-enter the Indies, the Dutch would not let him in.
[1] In his absence Sin Po appointed Tjoe Bou San both editor-in-chief and director of the newspaper, and Hauw resigned.
