If the wife earns it by herself, and it has no influence on your family's economy, then no matter how many things the wife brings to the family, it is no problem. Because filial piety is a matter of course, you should support it!
However, if your wife takes your salary at work, there is no bottom line for shopping at home, which has affected the family economy and the daily life of homesickness. Then you can stop it. Try to discuss with your wife and ask her to buy less things to take to her home.
In fact, I personally think that this is just the wife's concern and filial piety for her parents. As long as it is not too much, then turn a blind eye, which is conducive to the harmony between husband and wife. Of course, you can also buy more things for your parents.
