I feel that both of them are similar except HowNet. I checked on Taobao with paperpass, and compared with HowNet, it was 40% or 50% worse. But it is much cheaper than HowNet. I suggest you finish it yourself, check it on Taobao with paper, and then change it. But you should use HowNet at least twice (I think your school should provide HowNet for duplicate checking, and our school library has it). Determine your own repetition rate in the first inspection, and then slowly correct it according to the results of duplicate checking. If the repetition rate is high, we should be patient and correct it slowly. Over time, if you think it's all right after the revision, you must check it again with HowNet. This is to determine whether it can meet the standard. If it doesn't meet the standard, it can be revised again (even if the second inspection doesn't meet the standard, I guess it's not much difference). If it meets the standard, you can be practical.
