Why did ancient Chinese make bricks often? No. In ancient times, most common people lived in straw huts, and those who could live in wooden houses were considered well-off. Brick houses were very rare, usually only for kings, and even then, only in very prosperous times, kings could make brisks to build big palace, bridges, big houses, and big towers. Brick making was a symbol of prosperity in ancient time.

The Song Typeface of character Prosper is
Now we must ask: How did the traditional character Prosper become the simplified character?
Cursive Script of character Prosper
The first character is simplified, while the remaining five are the traditional "興". They are all written vaguely. The left hand is replaced by a vertical stroke, and the middle part sometimes looks like "月," "习" or "刁." Only the right hand is clearly written. The simplest is the bottom left, almost just four vertical strokes, with vague lines and two dots. Some are written even more simply.
This is the source of simplified characters. The four vertical strokes above were simplified to three dots, though it's unclear why not four. Perhaps people wrote three strokes, and the extra strokes were vague. Three strokes can represent many strokes.
Many simplified characters have traces of cursive script, so understanding some cursive script can help understand the origin of simplified Chinese characters.
