Excuse me, is the communication engineering budget major promising?

It depends on whether you do it well. You never know how the design budget and final accounts of the project are made, and it won't take long. But you still need to make some efforts to be meticulous, deeply understand the basic workload of each quota, the purpose of each quota, and selectively make the actual budget and final accounts.

If you can become a small expert, the general salary is still no problem.
