Is the transmission slipping in forward gears?
Have you checked for trouble codes?
Are you able to get into park?

It can forward when in "D". When turn to "R" for reverse, can feel the gear at "reverse mode", but it cannot reverse at all. Base on your experience, what's wrong is this? Where should I start to repair?

This sounds like the gear range selector sensor on the side of the transmission is bad not telling the computer the transmission is in reverse so no command is given.

Here is a guide to help you run some tests to confirm the failure and get it fixed.

Let us know what happens and please upload pictures or videos of the problem.
