This opportunity is good, especially the training in this highly professional technical direction. I have lived in Germany for 10 years. When I was working in a German company, I was sent back to China to be the head of a domestic company, and I was familiar with the personnel arrangement of German companies and the staffing of various departments. If a German company is willing to spend money and energy to train a technician in Germany, believe me, it is very rare. Even if you pay for it yourself, you will go as long as you give the opportunity. German companies attach great importance to the development and layout of technical personnel, even more important than management. The gains in these two years are far greater than those in China. As for German, it is unrealistic to learn it in two years. My master's degree and doctor's degree are both in German, and I can't understand German for seven or eight years, so I can learn to communicate as long as I learn English well. As for German, I won't consider it, it will waste time.
