Liu Fuyou has three signs, all of which are anti-counterfeiting through trademark registration. The first one is Liu Fu's Chinese characters, the second one is a hexagon with a blessing in it, which is called a hexagon blessing chapter, and the third one is the initials LF of the English abbreviation.

Among these three brands, LF is the most popular jewelry brand, accounting for 80% of all gold shops in Liu Fu.

As long as it is a regular brand, jewelry will have its own brand imprint.
