     Many large cities in the United States have an area called Chinatown. Each of them was set up by people

who came from China. For example, Chinatown in San Francisco, California, began in the 1840s. The Chinese

immigrants (移民) came to America to look for gold. Then the area they lived in later became known as

Chinatown.

     Chinatowns were also setup in cities in the western states of Oregon and Washington during the middle of

the 19th century. Many Chinese immigrants in these areas helped build the first railroad system across the

United States. However, after the work ended in 1869, many Chinese moved to the eastern and middle parts of

the United States.

     Chinatowns can also be found in cities outside the United States. For example, the first Chinese immigrants

in London arrived in the late 18th century. They were men who worked for the East India Company. Later, the

Chinese immigrants opened small stores and restaurants there.

     Today, many people visit Chinatowns. They have special Chinese gates and walking areas for visitors.

Chinatowns around the world are not only places where Chinese people live and work. They are also places

where visitors can learn more about Chinese culture and traditions.

  朱晖字文季,南阳宛人也。晖早孤,年十三,王莽败,天下乱,与外氏家属从田间奔入宛城。遭遇群贼,白刃劫诸妇女,略夺衣物。昆弟宾客皆惶迫,伏地莫敢动。晖拔剑前曰:“财物皆可取耳,诸母衣不可得。今日朱晖死日也!”贼见其小,壮其志,笑曰:“童子内刀。”遂舍之而去。初,光武与晖父岑俱学长安,有旧故。及即位,求问岑,时已卒,乃召晖拜为郎。晖寻以病去,卒业于太学。性矜严,进止必以礼,诸儒称其高

  晖刚于为吏,见忌于上,所在多被劾。自去临淮,屏居野泽,布衣蔬食,不与邑里通,乡党讥其介。建初中,南阳大饥,米石千余,晖尽散其家资,以分宗里故旧之贫羸者,乡族皆归焉。后迁为尚书令,以老病乞身。(选自《后汉书·朱晖传》,有改动)
