Being able to pay 3980 to study cross-border e-commerce has its own abnormal charges, and you still have to pay it. This is a complete IQ tax. Ugly, but straightforward. I hope you don't mind. If it is an online course, I suggest you ask the police uncle if there is anything that can help you. It seems that there is really no other way to solve it. Let's talk about it again: At present, if you want to do cross-border e-commerce, each platform has its own learning tutorial, which is very elementary and can be understood at a glance. If you think your English is not good, you can use translation software. If the page is too large, it is suggested that you can also use the translation function that comes with Google Browser for translation. If you are asked to pay for your study, you should think carefully. If the amount is particularly large, think clearly. After all, you are all adults, and brains are a good thing. Let's stop here. I hope my answer will satisfy you and give you reasonable suggestions.
