How to treat the phenomenon that mother-in-law values sons over daughters?

I have some suggestions for dealing with family relations:

1, a minute of humility, don't criticize everything between family members, give each other more opportunities, think more about each other, avoid unnecessary conflicts, and family ties are priceless.

2, a little surprise, creating a dramatic effect, often many contradictions disappear in jokes.

3. Divide the responsibility into two parts, take on your due responsibilities and obligations, do more for your family and think less for yourself.

4, binary communication, many contradictions are due to the lack of communication between family members, exacerbated the contradictions.

5, four points open-minded, life is short, to create a harmonious society and harmonious family, everything should be open-minded, don't haggle over every ounce, don't intrigue, don't be greedy for petty gains, be open-minded, and those who are willing to be grateful live a relaxed and happy life.
