    He was a poet known for the nostalgia he describes in his poems. Now, it's time: for us to express our nostalgia for this great writer.

    On Dec 14, 2017, the famous Chinese poet Yu Guangzhong passed away in Taiwan. Born in 1928 in Nanjing, Jiangsu, Yu studied in Sichuan when he was young. At that time, he had showed great interest in Chinese poems and spent a lot of his free time trying writing poems himself. Then he managed to publish his first poem at the age of 20. A year later, Yu and his family moved to Taiwan. He lived and worked there until his death.

    Nostalgia is Yu's masterpiece in which he expresses his homesickness for the Chinese mainland when he was in Taiwan.

    Published in 1971, the poem remains highly popular among Chinese speakers worldwide. Even those who know little about literature are familiar with lines from the poem. The poem is included in Chinese high school textbooks.

    Besides his achievements in poetry, Yu was also a successful essay writer, critic and translator. He once translated English poet Siegfried Sassoon's poem In Me, Past, Present, Future Meet into Chinese. It is regarded as an accurate and powerful translation, in which the most famous line is “心有猛虎, 细嗅蔷薇” for “In me the tiger sniffs the rose”.

    Yu spent his whole life writing. “The reason why I stick to writing till today comes down to my passion for the Chinese language,” he once said in a 2015 interview. He then added that this passion was strengthened by his love for his mother and His motherland.

    Now, let's appreciate the poem Nostalgia.

When I was young,                    But later on,

Nostalgia was a tiny, tiny stamp.         Nostalgia was a low, low grave.

Me on this side,                      Me on this outside,

Mother on the other side.               And my mother was inside.

When I grew up,                     And at present,

Nostalgia was a narrow boat ticket.       Nostalgia becomes a shallow strait.

Me on this side,                       Me on this side,

Bride on the other side.                 Mainland on the other side.

    One of the easiest things in the world is to become a fault-finder. However, life can be 1when you are not busy finding fault with it.

    Several years ago I2a letter from seventeen-year-old Kerry, who described herself as a world-class fault-finder, almost always 3by things. People were always doing things that annoyed her, and 4was ever good enough. She was highly self-critical and also found fault with her friends. She became a really 5person.

    Unfortunately, it took a horrible accident to change her 6Her best friend was seriously hurt in a car crash. What made it almost 7to deal with was that the day before the 8, Kerry had visited her friend and had spent the whole time criticizing her 9 of boyfriends, the way she was living, the way she related to her mother, and various other things she felt she needed to 10It wasn't until her friend was badly hurt that Kerry became 11her habit of finding fault. Very quickly, she learned to appreciate life rather than to 12 everything so harshly ( 刻薄) . She was able to transfer her new wisdom to other parts of her13as well.

    Perhaps most of us aren't as extreme at fault-finding,14 when we're honest, we can be sharply 15of  the world. I'm not suggesting you16problems, or that you pretend things are17than they are, but simply that you learn to allow things to be as they are—18most of the time, and especially when it's not a really big 19 .

    Train yourself to "bite your tongue" , and with a little 20, you'll get really good at letting things go. And when you do, you'll get back your enthusiasm and love for life.
