3. Pinch soft and hard. Pinch the crab's leg with your hand, if it feels very soft, it means that the crab is very empty, there is no meat, and the crab paste and crab roe cannot be very full. And if the crab legs are very hard, it means that this is a "robust" crab, indicating that the crab paste is rich in rolling crab roe.

4. Identify vitality. Energetic crabs are fresh and healthy. But one thing to note is that many crabs on the market are bundled and sold, which is for fear that the crabs will consume their weight and lose their legs due to excessive activity, in this case, we only need to touch the crab eyes lightly - energetic crabs will quickly dodge the protruding eyes.
