Graduation is naturally something that everyone is looking forward to, but when it comes to graduation, it is somewhat refreshing. Climbed the mast several times, needless to say, I don't deserve to be half a sailor; After listening for several years, can you dig up gold, silver, copper, iron and tin after several mines? I'm really not sure about myself, and it's not as easy as "if a worker wants to do a good job, he must sharpen his tools first". Climbing 20 feet into the sky and drilling 20 feet into the ground, I found nothing. Learning is "above, he looked for the green void, below, the yellow spring, but he didn't find the person he was looking for in either place." There is only one way left: to go abroad.
