Red gang refers to the craft of suits, usually referring to the craft of the old Shanghai Ningbo red gang master.

The price of a suit basically has two parts. One is that the fabric of a suit is usually 80 to 160 100% wool series.

The second is the finished product of suit craft, red band, hand-made and machine-made.

Usually 100 piece of wool (domestic fabric) is hand-made by the red gang master at around 3000-4000.
