Q: Can I bring live crabs or other fresh seafood on the Shanghai Metro?

A: Yes, but only under specific conditions. The seafood must be sealed in a sturdy, leak-proof container such as a foam or plastic box with absorbent material and no leakage or odor. It must pass security inspection and cannot occupy seats or block aisles. The package must also meet size limits: no more than 30 kg in weight, 0.2 cubic meters in volume, and a combined length, width, and height not exceeding 1.8 meters.
