Han Chan Piet was first appointed to the colonial bureaucracy when he was made his father's deputy in Surabaya, at an unknown date, with the title of Luitenant der Chinezen [REF].
In 1813, his younger brother, Han Kik Ko, Majoor der Chinezen, who had purchased the district of Probolinggo and had ruled in an apparently despotic manner, was killed in a local revolt - dubbed Kepruk Cina ('Attack on the Chinese') [REF].
