Hello, system configuration fee and system customization service fee must be paid. Agency operation service fee and custody service fee are charged according to your needs. If you have this demand, you can entrust a carriage loading service, and carriage loading is acceptable. But I need to remind you that a good and mature team, a team that understands the project, will definitely get twice the result with half the effort if they do operation and custody, so that you can make money and save effort. I hope Baidu will adopt it
