About a question in the movie "The Deadly Grass".

Many years ago, No. 9 Nathan Road was a cheap men’s haircut stall near the pier. dockworkers and small traders with little money in their pockets liked to go there to get their hair cut. Haircuts there are very cheap, and the speed is amazing, and you can get a haircut in no time. It's a pity that I can't compliment my hair-cutting skills. I can only guarantee a short haircut and it's cheap, but the haircut often makes people laugh. The older generation of Hong Kong people can't help but laugh when they mention the haircut at No. 9 Nathan Road, which is a perfect synonym for funny. So in "The Dead Man", Stephen Chow took out this familiar joke to Hong Kong people and re-arranged it - it should be said that the arrangement was quite successful. Even those of us mainlanders who don't know what No. 9 Nathan Road is, we also Will find it funny.
