I respect customs that emphasize gathering for meals and festivals. Over-the-top displays for appearances, like insisting on huge gift exchanges, should be reconsidered.

Respect for elders. I admire families that regularly check in on their elders and involve them in decisions. I think extravagant weddings just to show off are unnecessary and should be toned down.

Parents never apologize to their children even they've done wrong things because they are afraid of losing the prestige as elders. As a result, most Eastern Asian parents owe their kids a "sorry".

I admire traditions like respecting elders and valuing family bonds. Habits like excessive gift-giving for “face” should change to reduce social pressure.

When haviing meals with families, there's always a custom to let the elderly start eating first, and anther goes, unless all the people arrive can the meal really start.
As a adolescent, I can't totally identify with this face-saving act. For me, my elder relatives tend to step aside and ask another person to take the first eat. That's quite annoying while funny and unnecessary, just like pretending to grab the treat, which often makes juniors rather awkward and impatient. 
For the second one, I think is too harsh as will press people must arrive in advance so that they won't get discussed. And this can be a reason young people are reluctant for formal dinners with relatives to some extent.
(Above is about my private opinion, please agree to disagree😉)

Go home with familiers together at weekend.

I appreciate traditions where family members help each other financially or emotionally. Using ceremonies or gifts to compete for status feels superficial and should change.

I value families that teach children responsibility from a young age. Lavish banquets or excessive spending to impress others seem wasteful and could be simplified.
