I think these basic building blocks of home cooking also extend to family style eating at Chinese restaurants.
2 people = 2 dishes. 3 people = 3 dishes. 4 people = 4 dishes.
Don’t repeat cooking techniques (1 steamed 1 fried is ok, 2 fried is weird)
Have as many proteins as possible
One of the dishes is veg-centric
There’s always rice and soup
