Grammar Point:
The structure “A 沒有 méiyǒu B 这么 zhème / 那么 nàme Adj” is used to compare two things in Chinese, meaning “A is not as [adjective] as B.” It’s a simple way to say that one thing is less [adjective] than another.
Structure
A + 沒有 + B + (這麼/这么, 那麼/那么) + Adj.
这么 zhème is usually used for things that are closer or more immediate, like saying “this much.” On the other hand, 那么 nàme is used for things that feel more distant or general, like “that much.” Overall, the difference between them isn’t very significant.

Oh, boy! Let’s talk about Taiwan cockroaches! They’re like the celebrities of the cockroach world. Thanks to Taiwan’s picture-perfect weather and delicious food, these little darlings can grow up to a whopping 4.8 centimeters (1.8 inches) in length, leaving other cockroaches in the dust.
If that wasn’t enough to impress you, get this – Taiwan cockroaches are super friendly! Unlike those boring old cockroaches that run away from people, Taiwan cockroaches are the life of the party. They love to socialize and make new friends, so don’t be surprised if one comes running directly at you with open arms – er, legs.
And just when you thought it couldn’t get any better, these cockroaches also have a secret superpower: they can fly! That’s right, folks, these little winged wonders are taking the cockroach game to a whole new level.
