Many people are asking me how programmers get high salaries and how to achieve an annual salary of 40W+. In fact, it can be summed up in one sentence, your technology determines your ability and salary.
So what kind of technical talents can get a high salary in the Java industry?
Here is one of my summary techniques:

Every night from 8:00 to 10:30, Alibaba Daniel live-streams lectures on Java engineering, high performance and distribution, performance tuning, Spring, MyBatis, Netty source code analysis and other knowledge points. Friends in need can join our Java architecture/distributed/high-performance group: 626326599
Finally, I have compiled a systematic learning map:
Distributed Topics

Source code analysis
team cooperation
I have a dedicated exchange learning group: 626326599. There are new video updates in the group every day, and Daniel live broadcasts lectures every night.
According to incomplete statistics, as of now (2018.01), the number of Chinese Java programmers has exceeded 1 million. Moreover, with the continuous development of the IT training industry and a large number of fresh graduates entering the society, Java programmers are facing increasing competitive pressure. So, as a Java programmer, how to work hard to quickly grow into a senior programmer or architect, or what kind of technical knowledge system an excellent senior engineer or architect should have? Junior programmers who enter the workplace, and old programmers who start to be confused after three or five years of work, must face and understand the problems
