I am sorry for the language confusion. I also wish I could write in Mandarin.

The answer to your question is yes, the range is OK even assuming no antenna gain at each end.
The flat fade margin will be about 18dB, but over a 60MHz bandwidth you should expect to see dispersion fading if the reflection point on the ground (or any other object along the path) is visible from both ends.
