Poor souls, forced to play in that wind, dust and noise! Designated as catchment districts in which building is prohibited, these riverside areas lack public facilities like lavatories and places to buy food and drink. If athletes want to eat or go to the bathroom, they'll have to fend for themselves.
說來有些不忍，河川地裡運動，風沙大、灰塵多，而且為行水區的保育，河川地不准蓋建物，因此例如廁所、餐飲販賣部等公共措施一概付諸闕如，運動員想吃飯、方便，只好自己看著辦。
