2. Hand-pinching identification method: mainly check whether the cans are bulging. You can press the bottom and cover of tinplate cans with your fingers, and press the cover of glass cans, and carefully observe whether there is bulging of the can.

You can use a small wooden stick or finger to knock on the center of the bottom cover of the can and listen to the sound to identify the quality of the can. Good quality cans have a clear and solid sound; inferior and low quality cans have insufficient contents and large gaps, and the sound is turbid and empty, that is, a hoarse sound of "breaking".
