Emperor Kangxi had an original view of wind function.His observation on the difference of wind directions in Shandong and the capital has been erroneously taken as the evidence that he first discovered the wind field discontinuity in the past several decades.On the basis of analyzing the original papers,this paper points out the mistake.By giving two examples of wind's function on the formation of salt and white dragon dunes,it is also demonstrated that Emperoe Kangxi's knowledge of wind was also limited.
