Lin Xiaobei (played by Dai Xiangyu) talking about at one time going to the Singapore Grand Prix. This is not to be confused with the Formula One version, which only came about to Singapore in 2008. The predecessor first came about in 1961 and was discontinued in 1973. The version that Xiaobei was talking about had been taking place at the Thomson Road circuit since Singapore attained its independence in 1965, until the discontinuation after 1973.
What Lin Xiaobei (played by Dai Xiangyu) was referring to when reading out the newspaper headlines to Huang Jinhao (played by Eelyn Kok) was referring to the Vietnam War, and on the real-life Hong Kong actor Patrick Tse.
