Is it reliable to find a cargo ship to work in the same city of 58, without charging any fees, only charging 300 yuan medical examination fees?

Not reliable. There are a lot of false information on the internet about the so-called high-paid recruitment of seafarers and merchandisers. Basically, they are swindlers, who cheat money by handling passports, seamen's cards, visas, border defense cards, medical examination fees, training fees, insurance fees, meals, referral fees, deposits, security deposits, etc. , or temporarily arranged as a security guard for some reason (such as training, internship or waiting for some certificates ...).
