I see both Fung shu ming and Dr Yeung, the only advantage for Dr Yeung is you have no need to make booking, for Dr Fung, you need to make the booking around two weeks earlier, he is cheaper, seems to be concern you more, if you want to grant sick leave for more than 2 days, don't go to Dr Yeung, he always think that you have no need to sick leave so long even if you really need it, it made me feel bad but Dr Fung is good, seems understand you more
You can see Dr Fung only after 6pm at Yuen Long, Mon to Fri, After 2pm on Sat, if you want to see him at office hour, you can go to Jordon, and just book 3 days earlier.
