First of all, you must have a chef's certificate, which generally requires 1 or above. I also ask you not to get seasick.

You must have four certificates and a service manual to board the ship. If you are engaged in foreign trade, you must also have a seaman's certificate and passport. Exam 4 requires training. If you are on a special ship, you need some special training! For details, please consult the nearest maritime agency government affairs center.
