In spite of all these claims, most people would agree that there is little evidence that numbers have any influence on our lives. In fact, they say, the reverse seems to be the case. For one thing, we might expect calculators to break down every time they note the number 13, and for another, although every week has seven days we know that not every week is lucky for us.
Weighing the pros and cons of these arguments, I am inclined to agree with the latter point of view. It is obvious that there is no scientific basis for the belief that there is a connection between luck and numbers. All in all, it seems to me to be superstition.

3. My View on Job-Hopping
Job-hopping, or frequent change of jobs, is becoming increasingly common in China today. As the economy grows, more opportunities for employment are appearing than before. The result is that people, especially young people, are tempted to change jobs frequently, seeking higher salaries or more interesting positions.
Nevertheless, many people prefer to stay in their old jobs. This is partly because they feel loyal to their work units, and partly because they dislike the idea of having to spend much time training for a new job. In addition, although a new job may offer higher pay or more opportunities for promotion, it may be located far from home and be inconvenient to reach.
I think it is a good thing for the workforce to be flexible, so that new demands for personnel can be satisfied quickly. However, if a person changes jobs too often, he or she will cause losses to the employing units. Moreover, frequent job-hopping prevents a person from gaining valuable job experience and developing good work habits.
