       鲁达又道：“老儿，你来。洒家与你些盘缠，明日便回东京去如何？”父女两个告道：“若是能够回乡去，便是重生父母，再长爷娘。只是店主人家如何肯放？郑大官人须着落他要钱。”鲁提辖道：“这个不妨事，俺自有道理。”便去身边摸出五两来银子，放在桌上，看着史进道：“洒家今日不曾多带得些出来，你有银子借些与俺，洒家明日便送还你。”史进道：“值甚么，要哥哥还。”去包裹里取出一锭十两银子放在桌上。鲁达看着李忠道：“你也借些出来与洒家。”李忠去身边摸出二两来银子。鲁提辖看了，见少，便道：“也是个不爽利的人。”鲁达只把这十五两银子与了金老，吩咐道：“你父女两个将去做盘缠，一面收拾行李。俺明日清早来发付你两个起身，看哪个店主人敢留你！”金老并女儿拜谢去了。

       鲁达把这二两银子丢还了李忠。三人再吃了两角酒，下楼来叫道：“主人家，酒钱洒家明日送来还你。”主人家连声应道：“提辖只顾自去，但吃不妨，只怕提辖不来赊。”三个人出了潘家酒肆，到街上分手。史进、李忠各自投客店去了。

    Can you write down a Chinese word being read to you? Sometimes it can be difficult when you find the word is not included in most dictionaries.

    Lu Jialei, 14, from Hangzhou Foreign Language School, won the CCTV Chinese Character (汉字) Spelling Contest on Oct 18^th, 2013. About 160 people competed. The host read a word to the contestant, explained its meaning and gave sample sentences. The contestant was required to write down the word.

    Winning the contest was a “surprise” to Lu. “I was not the smartest one,” she said. “But I paid attention to details.” To prepare for the contest, she and her teammates studied the Modern Chinese Dictionary for 10 days. There are more than 56,000 entries (词条) including characters, words and phrases in it. She also had a secret weapon. She studied how Chinese characters were formed.

    “When others paid attention to the plot of a story, she looked at how authors use words and sentences to express themselves,” said Su Yunsheng, Lu's Chinese teacher. Su is happy to see students like Lu find the beauty of Chinese language.

    “Besides using something Chinese and having Chinese traditional festivals, learning to write Chinese characters is also an important part of inheriting (传承) Chinese culture,” said Su.
