I think this is a reflection of city development in Singapore, which has a similar population as Hong Kong. Sadly, people have to move their deceased family to somewhere else because of real estate development. It is also a reflection of history. Their ancestors moved to Singapore from mainland China for better opportunities. And that is why they preserved the tradition of visiting their ancestors during Qing Ming. Lastly, I think this movie also portraits the tension between the rich and poor. One of the guys complained why they have so many golf courses but not enough cemetery. When a city becomes more developed, it is more difficult to preserve cultural traditions, which is the downside of urbanism.
