【正文】 m of big ads saying Sales on Chinese Valentine39。s Day! in shops, hotels and restaurants. But few young women will mark the festival with their boyfriends, or take part in traditional activities to pray for cleverness. A largescale of exhibition on the Silk Road opened to the public in the National Museum on Thursday. The exhibition displays more than 400 treasures from Shaanxi province, Gansu province and 14 other regions. It is largest scale exhibition that shows the history of the Silk Road in recent years. As APEC is going on in Beijing, the exhibit aims to show the world this brilliant section of history. The Silk Road is a series of trade and cultural transmission routes that were central to cultural interaction through regions of the Asian continent. It connected the West and East by linking traders, merchants, pilgrims, monks, soldiers, nomads, and urban dwellers from China and India to the Mediterranean Sea during various periods of time. I met my dear hubby in 2020 the second year I was in my school and it was the first year when he came here. We became colleagues. And there was nothing special happening during that year. He was just a kind and humble brother graduated from the same college as me. But we did not know each other till he became my colleague and his office desk was just in front of me. There was only a glass between us. So actually we could see each other when we both look up. But it is not the main reason that really draws us close. How we bee close to each other was something seems quite natural. We went out to play badminton with other colleagues and we sometimes chatted for a while. He is a man of few words but somehow sometimes will say something really humorous. Then one day, to my great surprise, I found a pot of beautiful flower on my desk. It was just the flower I had talked about with my colleague the other day, and I thought it was her who put the flower there. But the truth is not. It was the humble guy sitting in front of me. He just simply said ,”well, I caught sight of this flower and thought that it’s beautiful and you may like it”. I wonder why I was moved because of these simple words and present. Maybe it is the sincerity and the true self that impress me. I thanked him and some colleagues walked past my desk would appreciate the beautiful flower and they noticed that something romance happened there. Then later on, there were some little surprises once in a while. Once, there was something wrong with my drawer and I had plained about it unconsciously. And he fixed it for me. Then the other day, he placed several pink diamond roses beside the flower with a piece of paper saying” I love you more than I can say! Diamond stands for marriage, rose stand for 蘇州工業(yè)職業(yè)技術(shù)學(xué)院 25 love. I hope you are mine, bee my wife. You are the only girl who I really want to spend the rest of my life to stand by.” Although there were some grammar errors but I got what he meant. He meant so clear and so direct. And actually, I accepted him some days earlier. I was just waiting for him to break the ice. So finally, the mon interests and the mon understanding brought us together. Some people say the relationship and the feeling will change after getting hitched. You will find that love is no longer strong and there is always lack of passion and what’s worse you may find out many bad habits of your partner, which never appear when you are first in love before the marriage. It seems that many faults turn up after you truly living together and see each other’s face the moment you open your eyes in the early morning. But after almost 4 years from now, I do not feel any negative change in our relationship. During all these years, we know each other better and we bee more tolerant about each other and I realize that if you really love a person you will accept his imperfect. And what is the qualification of a good husband? Once I was chatting with my colleague about this issue. And one of the qualifications I thought was that he must be a good cook. But to my surprise, my colleague said that a good husband must be someone who makes big money. What made her think so was quite beyond me. Maybe I am not sophisticated enough and what I want is just simple life style. The most enjoyable thing is that we go to the market to buy vegetables and other daily stuffs if we both have time. Maybe he is a housebound husband and I love housebound man. And there is another reason why We love going to the market. That is because we sometimes will get some surprises. The surprise is saving little fish which are disserted by the fish mongers. Because these fish are swellfish. Then we will collect them and set them free into the river. Swellfish are lovely creature. When they look like a little submarine when they are swimming in the water and look like a meat ball when you hold them in your hand. And if they are scared, they will swell and look like a little ball. Every time we see them swim away and we feel their happiness of returning home and this also make us cherish life. Maybe some will consider these behavior as something childish. Well, that is fine with us. We love doing these together and feel happy that is what it is all about. My dear hubby is a kind hearted man and he love animals just as I do. I am lucky to have someone who can be both my intimated soul mate and my forever friend.
