A problem in the movie Counting Dead Grass.

Many years ago, No.9 Nathan Road was a cheap men's barber shop near the pier, where dockers and small traders with little money in their pockets liked to have their hair cut. Haircuts there are cheap and the speed is amazing. You can get a good haircut soon. Unfortunately, the skill of cutting hair is not flattering. It can only be guaranteed to be short and cheap, but the haircut often makes people laugh. The older generation of Hong Kong people can't help laughing when they mention the haircut at No.9 Nathan Road, which is simply an excellent synonym for funny. So in "Cursing Dead Grass", Stephen Chow took out the joke that Hong Kong people are familiar with and rearranged it-it should be said that the arrangement was quite successful, even those mainlanders who don't know what No.9 Nathan Road is will find it funny.
