Nancy Kwan's character sings "Grant Avenue", a big production number in Chinatown. The lyrics incorrectly identify a "cable car" as a "trolley." Cable cars move by gripping moving cable that runs under the street. A "trolley" uses a "pole" which connects from the roof to an overhead wire which powers the car. Cable cars do not use poles or overhead trolley lines.
The New Year referred to in the film is the Spring Festival which marks the beginning of a new year in the lunar calendar. This is characterized by greeting 'Kong Hei Fatt Choi' (in Cantonese, the main dialect spoken in Hong Kong) which Sammy said to the family watching the parade and the handing out of red packets in another scene. Also, Wang Ta mentioned that it was year of the Ox from the Chinese zodiac. That being the case and assuming it was set in 1961, the first day of the new year would be on 15 Feb, a Wednesday. Yet in a scene of the following day, Wang San said he wasn't it school because it was a Saturday.
