trees and weird chinese fruits

the pink fruit is actually a dragonfruit, about 10 grow every year, the green one is an unripen one, and thier are some weird miniture apples, all from my summer home ~~~these weren't so hard to grow, the tree took awhile to gow (instead of seeds, my mom bought a baby version of it, to avoid the hassle). You can only eat what's inside the dragonfruit, not the 'stem'(you can try but it wouldn't taste that good).
