Preface:

Every Internet worker has an Ali dream, and the realization of this Ali dream, in addition to luck, but also rely on hard work.

When I first entered Ali, I was a member of P5. At that time, the school recruitment was successful, and I soon received the letter of intent from Ali, and finally succeeded in joining Ali. This is ali’s most common rank, and it is not easy to rise above the P5.

Ali this is my work in just five years, is now serving the P8, soon, of course, is just rising P8, actually in this five years of ali, this is my third time of promotion, a lot of friends around also curious how I insist on down, P5, when I got what I will know that I have had a watershed.

To this day, I still believe that my efforts are worth it, because I always believe that luck only comes to those who are prepared.
