Some chinese translation of http://brainden.com/logic-puzzles.htm is not correct, for example
An Arab sheikh tells his two sons to race their camels to a distant city to see who will inherit his fortune. The one whose camel is slower wins.
but chinese translation (一个阿拉伯酋长要求他的两个儿子比骑骆驼到远方的城市去，看看谁骑得慢) means
An Arab sheikh tells his two sons to race riding camels to a distant city. The one who riding is slower wins.
Correct translation should be 一個阿拉伯酋長告訴他的兩個兒子用駱駝比賽去一個遙遠的城市，誰的駱駝比較慢就勝出，贏了可以繼承他的遺產
This make the answer doesn't make sense to switching camels, how
