I am confused,
everytime when I restart the instance, packages I installed/files I created are gone.
The instance is "blank" like the brand new after I created.
Is it the design/default config of Openstack?(It seems ridiculous...)
Is it related to the way I start the instance(from image)? why?
What should I do if I want to reuse the data in instance?

This is not a default design kind of thing. Can you tell which hypervisor you are using . What is happening is the disk that is created for the VM is not in good shape as whatever you are writing on it is getting erased.

Also provide weather Cinder is also involved in your setup ?

Running Kilo on RHEL7 and hypervisor is KVM. the steps of my operation:
1. create an image
2. create a network
3. create a flavor
4. create the instance by 1/2/3
5. login instance, create file(eg. vi)
6. restart(or stop/start) instance
every thing is fine except the file in 5 is gone.

cinder, in my case, is not involved.

What are the specs being provided while creating the flavor ?.. Also while launching the instances there would be logs of nova-compute coming can you please provide that.. Make sure debug is set to true in the config file

Thanks a lot ,Prateek!
By the clue from your answer, I realized the problem is about the image I used.
The only image I used in OpenStack is a customized RH7 from my customer. I tested several other images, they are working fine.
Now I'm aware of it.(I'm kind of stupid ^^)
