Setting off firecrackers tends to be associated with it happening on festive occasions like during Chinese New Year, not to wish someone luck with being a dance hostess, like what Xiaobei (played by Dai Xiangyu) did to wish Jianhong (played by Jeanette Aw) luck in her new job.
Television was still considered a novelty in Singapore in the 1960s (when it was introduced in 1963), and so to see Zhihao (played by Elvin Ng) getting obsessed with whatever was on with the television on display at the Qin family shop, first seen in Ep 10 (2009), may not be uncommon.
All the roads and streets that Xiaobei (played by Dai Xiangyu) mentioned to Jinhao (played by Eelyn Kok) after her singing audition still exist in Singapore, along with North Bridge Road, where the drama series is being set.
