Even if you have English subtitles, you won't be able to understand it. The chinese words have the same pronunciation but different meanings. They are just making jokes and ideological jokes. This is a culture belonging to the Chinese circle. So when you read the English text, you may not find it funny.It's like the knowledge of a region's culture when they use it to make a joke, but if you're not from that region, you may don't understand what the culture means.
