Three Fruits Lake.
Surrounded by mountains, the little lake's ripples reflected colorful lights from the sun.
In a four-square house next to the little lake was a circle of tables and chairs. A bunch of men and women with swords was sitting at the tables, registering every person that walked up to them.
The registration line was really long, folding back on itself multiple times. It filled up the entire marsh area around the lake.
Some were middle-aged with children, some were solitary people dressed like the powerful, and some were rich families with guards. All of them were here to register.
"Hey! Brother Lu, we meet again."
At the end of one of the lines, a well-dressed young man surrounded by bodyguards greeted the black-clothed man in front of him.
The man in black glanced at him expressionlessly, and didn't answer.
ED/N: So, about the two names. One was their full name (surname and first name), while the other was this so-called courtesy name, which was given to them by someone (like their teacher I guess), though some came up with their own courtesy names themselves. It was the courtesy name they used in social interactions and were adressed with.
Let's use an example: Sun Tzu. His actual name was Sun Wu (Sun Tzu as we know it in the west actually means "Master Sun", "tzu" is honorofic), while Changqing was his courtesy name.
Overall it's a bit complicated, so I'm not sure if the courtesy name replaced only first name or the full name, so go research it if you're curious. Google-sama is ready for deployment.
