How to spend four years in e-commerce major?

Personally, I attend classes as soon as I start, work part-time on weekends, and go to the library or other schools in my spare time. I think I, a junior e-commerce student, have the most say in this question, so I will talk about the hard road of e-commerce in my university. E-commerce is a pit, into the pit should be careful! Advice from an old schoolmaster who was tortured! At first, I knew nothing. Hear the name and Baidu Encyclopedia. I thought this major was quite high at that time, and the name sounded good for employment. Then ..... this major is an interdisciplinary subject of economics and management. When I was a freshman, I heard from the counselor that this major is a combination of many disciplines, a panacea for all industries, and an important talent training for counterpart enterprises in 2 1 century. At that moment, I heard, "Wow! This is amazing! " Then, the old man who has been ill in bed for three years now finally knows that crossing is learning miscellaneous things, and the key is not learning well! You have to learn everything. What database, web design, java, accounting, finance, management, marketing and so on. A head is four or five times as big! I know all about cps, cpc, cpm and crm, but as my predecessor in a company said, "This professional interview looks ok, but the background familiarity is really not as good as that of a month's customer service." As far as everything we have learned is concerned, we have learned everything. This knowledge is also very useful in telling the truth in e-commerce, but after I went to the internship, I clearly knew the difference and asked myself, "What have I learned!" However, it's interesting to tell the truth in college. The suggestion is to choose one of so many miscellaneous things that you are interested in and get in touch with the outside world. The ivory tower really won't stay long. Come on!
