Refuse, you just need to find you again and again, just like I do operation and maintenance, and then once I quit my job as a designer and was asked to get one. I played PS for 4 years and became a designer, and then, you know, I was asked to design, and I didn't look for a design. The key is that there is no money for design and no salary increase. Then, of course, after I graduated from computer, I was asked to do all kinds of related things, such as repairing printers, teaching office software, monitoring, TV and telephone line maintenance. I will repair the phone in Netcom for three years, and then I will repair the led now, because I understand the principle of this thing and give it to me once I fix it. I was looking for maintenance. After the maintenance expired, I asked them for 1 time, and the result was 150. The most important thing is that the salary is still 2.5k, which is the salary of our fourth-line enterprise operation and maintenance, so remember that I am an introverted honest man, and when others come to you, you will say no, I haven't done anything except my own work. This is my 14 years working experience. For example, I need help with my pictures and the work of the doorman, just because I am an operation and maintenance person and I am honest and introverted.
