To talk chèyècháng tán all night long
All night long chèyè
All night long; all night long.
Study all night long.
Long talk cháng tán
Long talk, talk freely.
The fourth chapter of "A Dream of Red Mansions": "This is a private room. If you want to talk for a long time, why not sit down." It's quiet, you might as well stand aside and have a long chat.
