Note that the buying of camera is also involved in services provided (salesman service), no matter what goods the tourist bought. Therefore it is counted in invisible trade account (credit).

就算相機是good
但買的時候salesman提供的是service (例如promotion, discount推介等等)
我們計current account時 有service的話會先計service
如果分別計算visible trade和invisible trade, current account便會有double counting.
