Kwun Chung is the original name It erroneously became known as the Jordan area becuase the MTR station is named after Jordan Road instead of Kwun Chung and in HK most people know a place because theres an MTR station I added a note in the text indicating that Waterloo station was changed back to the original neighborhod nameYau Ma Tei otherwise Im sure residents who dont live in that area would have called Yau Ma Tei the Waterloo area
