people and goods over and along the river. They also helped to load ships in the river and carry goods to the European merchantmen at Whampoa. Their presence was useful to the occupants of the Foreign Factories during periodic conflagrations. For instance, a painting of the Great Fire of 1822 shows residents viewing the fire from these boats, their main refuge in time of such emergencies.28
Interestingly enough, people of this type - perhaps even from the Canton group accustomed to foreigners - were of immense help to the British when they first established themselves in Hong Kong as providers of many essential services.29
Other groups of Tanka constituted the sea fishermen whose craft, large and small, were to be found all over the Delta and the islands outside it; and as we shall see further on in this talk, they provided the 'outside pilots' who assisted foreign merchant vessels to get safely into the Macau Roads.
Personnel directly connected with the China Trade
We may now consider seriatim, the various personnel encountered by foreign merchants and ships' officers during their time in China over the trading season of the year.
The Hoppo30
The Hoppo was the official at the head of the maritime customs, controlling the revenues accruing from the foreign trade. Representing the ministry of finance in Beijing (hu pu) he was dubbed with this title in error by the foreigners. This lucrative office was often filled by a Manchu. The Guangzhou Custom House is shown in Plate 5.
There were Hoppo in other maritime provinces of China, but the Canton Hoppo was the most important owing to the foreign trade being confined to Canton. His circuit eventually included five sub-stations and some sixty other collection points, the catchment for the coastal and inter-national trade. International trade was itself divided into Chinese, Asian and European, each taxed at a different rate; the Governor was left with control over internal trade.
