Which networking course is best for future？

This issue seems to be very difficult to answer. I only wanna say that international trade and the big data industry are now relatively good developments. 

It should be said that international trade and big data are developed on the basis of the Internet. As one of the new economies, the Internet carries thousands of consumer data. 

These data are the sources of trade information which are favored by all industries. Therefore, if there are more promising industries now, it must be a cross-border e-commerce platform with trade big data.
