When she saw an old beggar, she took the cold, rough hands of the woman with her warm, clean hands, and gave the woman some warm bread and helped her put on a pair of new gloves(手套).The woman was surprised for a few seconds, then burst into tears, saying “for the first time I feel respected(尊重)”.Cai said, “A beggar’s life is very hard. That’s why I want to help them.”Cai was one of 14 Tsinghua students spending Christmas Eve among the poor. They walked in the cold wind along the streets from 4to 7 pm on Friday, visiting 15 beggars in Beijing’s Haidian District.They brought bread and gloves with them, and stopped to greet beggars and offer them some of the warm food.

She went to his room and asked, “Son, what was it? Was it the nuns (修女)?”Little Tommy looked at her and shook his head, “No.”“Well then,” she asked again. “WHAT was it?”Little Tommy looked at her and said, “Well, on the first day of school, when I saw that man nailed to the plus sign, I knew they weren’t joking.”5.
