    Growing up to be independent (独立)

    Growing up is not always easy. When facing difficulties, courage arid a spirit of independence can be more

useful than crying for help. That's what Hong Zhanhui's story of growing from boy to man with family

hardships tell us.

    Hong was born in 1982 in a poor family in Yihua County, Henan province. When he was only 11, his father

became mentally (精神上) ill and one day came back with an abandoned (被抛弃的) baby girl. A year later,

Hong's mother and younger brother both left home because of being poor and pressure from his ill father. Their

burdens (负担) fell onto the l2-year-old's shoulders: to treat his father's illness, bring up the adopted (领养的)

sister Chenchen, and to go on to study，Hong didn't give up. Since a young age, he has worked in part-time jobs

to feed his family. At they same time, he has studied at college. To take care of Chenchen, he worked hard to

rent a room near his campus for her, and send her to school. After Hong's story went public, people were

moved to tears by his selflessness (无私), Hard as his life was, Hong didn't abandon his father and the adopted

sister because they needed his help. With his hard-won money, he even helped other students struggling against

misfortunes (厄运).

    Today when many tend to Worry more about their own happiness, Hong's deeds remind us of what we

usually neglect (忽略): love and care for others. Without these, none of us could survive Hong turned down

donations from others. He said he felt encouraged by kind offers but he could depend on his own work.

    Short of money to buy food, the boy climbed tall trees to get birds' eggs for his baby sister. He walked two

hours at weekends to buy different things to sell around his school to make money. Through his hard life, the

boy developed an ability to rise above misfortune that made him a hero in people's eyes.

    Hong's story shows that with love and willpower (意志力), no hardship can defeat a person but himself. So

when facing difficulties don't complain about bad luck. Consider what more you could do for your family and

society and you'll find the world smiling back.
