These sailors generally went on leave upon docking in German ports; in time, Chinese communities developed there. The Chinatown in the St. Pauli quarter of Hamburg (around Schmuckstrasse), Chinesenviertel, eventually became the largest Chinese community in Germany. By the time the Chinese consulate was established in Hamburg in 1921, more than 2,000 Chinese persons resided in Germany; professional sailors aside, the vast majority were in the catering and entertainment industries, as proprietors of Chinese restaurants, bars, cafes and dance halls.
