I found more problems.
Inside my car, I found one extra screw, which is same as the one
to fix the cd/radio, but there already have screws in the two slots.
There is moist/water inside the rear light, I can see it clearly.
So, I believe this body work is not a decent work, it's a mess.

According to my experience, I'll never trust the words, "I'll repair
it and it will look like brand new!".

Thanks, all.
