1, Can you provide a simple tutorial (or web page address) of how to
reverse-engineer a Linux ALPS driver if possible? I have very basic
programming knowledge(shell script, read basic C code except hardware
driver). Maybe, I can provide more detail hardware information about
this ALPS touchpad in this way?

I did a write-up a while back about how I did it.

2, Is there a tool, it can show the message when I operate on touchpad
edge scrolling? So, according to the output, it is able to get a dirty
solution about edge scrolling function of Lenovo G360 touchpad.
The funciton of "disable touchpad when typing" has a solution using
python script I have mentioned in the previous posts.

I'm sorry, I can't quite tell what you're asking. If you're asking for a
way to enable edge scrolling without having a functioning touchpad
driver, I don't know of any. I doubt it's even possible to detect that
you're near the edge of the touchpad with only relative motion events.

3, If you are interest in this and have time and it is helpful, I can
provide a root password for this laptop to you and run ssh service for
you all the time. Then you can operate this laptop via ssh connection
in this way. You can do anything on this machine even format the
disk :-)

I'm afraid it's just not practical to do this remotely. Being able to
physically interact with the touchpad is pretty crucial.
