Maoli is Canto transliteration of "mullion". In the early 20th century British foreigner teach HK people architecture. At that time building there had a lot of large windows and balconies. The main pillars of these windows and balconies are called mullion. Hong Kong people who do not understand English heard the foreigners pointed to a large wooden pole called "mullion". The wooden pole are standing there like stupid people.
