Karl Gützlaff
Between September 1842 and August 1843, Parkes served as a clerk under Karl Gützlaff, who was appointed as a civil magistrate in Chusan after the British occupied the island. In August 1843, he passed the consular examination in Chinese in Hong Kong and was appointed as a translator in Foochow in the following month. However, as there was a delay in the opening of Foochow port, he was instead reassigned to serve at the consulate in Canton and as an assistant to the Colonial Secretary of Hong Kong.
