How to go back from WOW to Hongkong Yau Ma tei station?tnx!

I suggest you take SZ West Express Line from WOW and get off at Mong Kok, where you can easily take subway or bus to Yau Ma Tei.

One of my friends told me that the Express Line also stops at Yau Ma Tei, Hong Kong. So you can confirm that with the driver. It will make your travel easier.
