I think weekend dinner is important in china.
Because it's a relaxing and union time for the family .
As we know . Some people don't live with their parents together in daily life . They work or study in other places.
They are very busy.Some of their tours are very far .
Sometimes they only can come back home on weekends. This is a relaxing time ! Usually the family sits together and has a big dinner .
They don't need to think of their work,money or study .
They have more time to have a free chat,taste the dishes . At the same time . They can share the news of socity, school,study,and so on.
Nowadays the soctyis more and more busy.
So in my opinion weekend dinner is more and more important.
