As an adult in Shenzhen, no matter what industry you are engaged in and whether you need to use English at work at present, if you don't know English at all, you should start learning as soon as possible, because opportunities always belong to those who are prepared. When a job that requires English is in front of you, it's too late for you to start thinking about learning English. Since there are many ways to learn English, you can study by yourself or online, but in fact, when you have relatively ample time to learn English, it is undoubtedly a better way to study offline. High quality is not only an interactive and interesting classroom atmosphere, but also the teacher's supervision, tracking and assessment of your learning progress, which is also the guarantee for your continuous progress in training.
