Before 1667, 1 convertible 16 HK dollars, after 1967, 1 convertible/4.55 HK dollars. For example, in 1962, the average handyman is about 30~50 a month, and two yuan a day is already very exhausting; 1967 factory workers are probably plumbers every month100 ~150,200-300. For example, in the late 1960s, the minimum wage was 36 yuan, and the student ticket for a movie was 5 points. Now the minimum student ticket for a movie is 30 yuan, which is 600 times higher. By analogy, the current salary of 2 1600 yuan can only be offset by the salary of 36 yuan in the late 1960s. Moreover, it is the most conservative statistic, because the most expensive adult ticket at that time was 20 points, and now the middle-priced 60 yuan ticket has increased by 300 times.
