Explosive development of technology and science have been done in the past years.  The dramtic changes in this society seemly make our grandparents can not keep space with modern life. Somebody may wonder whther the advices from our grandparents have use for their grandchildren. Indeed, our grandparents might not be familiar with some advanced technique or some new topics. However, I must admit that suggestions from our grandparents are useful in many aspects.As a matter of fact, many pricinples could not change constantly. In this modern society, many things change rapidly. But there are also some others could often change. Like some pricinples about how to get along with other people and the attitude toward troubles, these concepts are important in daliy life and could not change with the improvement of technology. For exapmle, I remember that when I was 12 years old, I had to leave my hometown to a new city and entered a new school. Actually I was a little bit nervous in that time due to I was a sham person. My grandpa told me that it is a good idea to smile to every stangers in my new class.  He said that he never did not like a person who was smiling to him and he believed that a friendly smile could reduce the distant bewteen people. I followed this suggestion and I made a new friend in the first day and we keep in touch until now. I think this pricinple is useful for us not only in present day but also could work in the future.As is known to all, rich experiences  from our grandparents enable us to avoid many mistakes. Grandparents have undergone many things and faced a lot of troubles even met so many people. Compared with us, they have rich experience to meet various situation and notice the truth in a short time. For instance, my cousin Jane knew a friend who told her that she can help her get a good job when Jane graduated from univerisity. I remember that it was a definite attracting job for many university students. But after my grandpa knew  the whole details about this job and this friend, he told  Jane maybe this person coule be trusted. Although Jane was not willing to give up this chance, she finally followed my grandpa. And she felt luck to  do that because that person is acutally a liar.Admittedly, in some case the advise from grandparents are useless. With the developent of technology, it is inevitable that our grandparent could adapt this modern socity well. Many old people could not use advanced tools like cell phone or computer and they even treat them as toys. For example, my grandmother always persuade me to give up using Ipad since she think it is just for fun and harm for my eyes. She cannot understand that Ipad is an important tool for me to finish my paper and look for many useful information. It is obvious that this suggetion is not meanningful for me and I will not follow this.Although some advices from grandparent might not be suitable for our modern society and they might not understand many new ideas and concepts, we cannot deny that the suggestions from out grandparent can help us lot in many aspects. They could notice some mistake you made and help you correct it. It is real benefical for us to obtain more information and knowledge from our grandparents.
