Hello , please help in evaluating this information, and an amulet from the experts on the Far East .
In my explorations is scant Lao Tzu (old child). In the late folk mythology of China, he was honored as the head of the caster , as well as the patron of blacksmiths , silversmiths and goldsmiths , grinders , cups , and manufacturers of chopsticks . Depicted as an old man riding a bull.
 Stamp a Word as a " pure silver " , which corresponds to the material.
Weight in '48 Dimensions 5.5 x 6.5 without the bells, bells with L = 12 cm .
Something similar is seen as decorations on knives and belts from Manchuria.
Is this true? Are there any other kind of information on the application of the subject ? And what is its cost.
