To send New Year's gifts to your mother-in-law, you should combine your understanding of her preferences and needs, and give gifts that cater to her preferences. In addition, your wife's opinion is also very important.
1. Your mother-in-law gave you her beloved daughter, so you should care about her like a mother. You can go to the mall with your wife to choose a beautiful cotton jacket for her to wear during the New Year, or you can choose warm clothes, cotton shoes, etc. to show your thoughtfulness and care for her.
2. Your mother-in-law is old and she is not able to do housework. As a filial son-in-law, you might as well buy a fully intelligent dust collector for your mother-in-law to help her reduce the burden of doing housework, which is also a real concern for her.
3. When sending New Year's gifts to your mother-in-law, such as oil, rice, meat, eggs and the like, your wife should have prepared them. You'd better choose a larger gift to be able to show it off. For example, giving her a gold necklace or a jade bracelet would be a good match for the old lady's wealthy temperament, and she would inevitably praise you as a filial son-in-law in front of others.
