What should I write in dormitory calligraphy and calligraphy?

The bedroom is a place to rest every day and a safe haven after a busy day. Hanging calligraphy works should be elegant and quiet. I suggest the following:

1, the book is full of stone, and there are herbs in the room;

2, static to cultivate one's morality, frugal to cultivate one's morality;

3. Not indifferent, unclear, not quiet, not far away;

4, contentment is always happy;

5. Do the right thing.
