Fung Ahok, a native of Whampoa, was one of the earliest Chinese ever to visit Germany. During his stay, several German authors described the two varieties of Cantonese spoken by him and his fellow traveler, Fung Asseng, a native of Xiāngshān. Meanwhile, both Fungs themselves also produced abundant manuscripts reflecting their Cantonese phonology, which can be believed to be of great value for exploring Early Cantonese. This paper aims to investigate the various materials left by Fung Ahok and some German scholars on Cantonese transcription and thus reconstruct his personal phonology.
