They are the same fruit. One is the name from home; the other is the name that came back from abroad.
In short: like a kid called by a pet name at home who takes an English name abroad. Back home, everyone starts using the English name, but it's still the same person.
It's not the name. It's these things:
The pricey "qiyiguo" in supermarkets is mostly imported by big New Zealand brands. The cost comes from the variety, the standards and the shipping, not the name.
The world's biggest grower is China.
Zhouzhi, a single county in Shaanxi province, can produce several hundred thousand tonnes a year. Home-grown fruit can be just as good, so don't hear "mihoutao" and assume it's the cheap stuff.

A place where you can go in but never come out, not even light. What it is, why nothing escapes, how we 'heard' two collide, and why Earth is safe.

When sugar and protein bits get hot they "hold hands" and make hundreds of aromas and a golden color. Why boiling doesn't work, and four searing tips.

The ten cloud types, learned through five Latin roots and a three-story sky: why "alto" clouds aren't the highest and which one brings thunder and hail.

Cities get buried by layers piling up in place: rebuilding on ruins, volcanic ash, floods and sand. Will the ground reach space? No, Earth's surface works like a slow conveyor belt.
