It may be due to the author's love for "Happy Together". After watching "Zero Celsius", I couldn't help myself and couldn't help but fabricate another possibility between Ho Baorong and Li Yaohui. But he was afraid of offending the two of them, and he didn't want to rashly rewrite their original stories by taking their names and spending every penny. So just think of it as a joking joke about my love for the film and its people.
