Observe the color of the meat, the texture of the meat, the connection between red meat and white meat, etc.

1. Observe the color of the meat: Normal meat should appear red or pink. If there are large areas of green or gray on the surface of the meat, it is a sign of lymphatic meat.

2. Observe the texture of the meat: Lymph meat will taste more viscous than normal meat, and the internal particles are hard and difficult to chew.

3. Observe the connection between red meat and white meat: in the case of lymph meat, the connection between red meat and white meat is not obvious and will be intertwined. In the case of fat, the line between red meat and white meat is relatively clear.
