I also studied Java. I used to work in a company in Suzhou, which was opened by a Taiwan Province man. Then the boss ran away and the company broke up. Now in Nanjing, I have at least a stable job, also engaged in Java, but few people accept it. The words in Qingdao are just so-so. Several people who study Java together often chat and think that this Java in Shanghai is better. All the above are my personal opinions.
