Generally speaking, training is not recommended, because even if you go, you can't learn. Studying too long is a waste of time. You can watch some videos of general skills yourself, but if you want to raise more money, you have to learn a full set of professional skills, otherwise you will only lose money. At the beginning, I also looked for a lot of technical information. Finally, I feel that the technology of the Oriental Fisheries Teaching Material Network is very scientific and comprehensive, which makes me learn a lot of technologies that I can't find online.
