触龙说赵太后

       赵太后新用事，秦急攻之。赵氏求救于齐，齐曰：“必以长安君为质，兵乃出。”太后不肯，大臣强谏。太后明谓左右：“有复言令长安君为质者，老妇必唾其面！”

       左师触龙愿见太后。太后盛气而揖之。入而徐趋，至而自谢曰：“老臣病足，曾不能疾走，不得见久矣，窃自恕，而恐太后玉体之有所郄^①也，故愿望见太后。”太后曰：“老妇恃辇而行。”曰：“日食饮得无衰乎？”曰：“恃粥耳。”曰：“老臣今者殊不欲食，乃自强步，日三四里，少益耆^②食，和于身也。”太后曰：“老妇不能。”太后之色少解。

       左师公曰：“老臣贱息^③舒祺，最少，不肖，而臣衰，窃爱怜之，愿令得补黑衣^④之数，以卫王宫。没死^⑤以闻！”太后曰：“敬诺。年几何矣？”对曰：“十五岁矣。虽少，愿及未填沟壑而托之。”太后曰：“丈夫亦爱怜其少子乎？”对曰：“甚于妇人。”太后笑曰：“妇人异甚！”对曰：“老臣窃以为媪之爱燕后，贤于长安君。”曰：“君过矣，不若长安君之甚。”左师公曰：“父母之爱子，则为之计深远。媪之送燕后也，持其踵为之泣，念悲其远也，亦哀之矣。已行，非弗思也，祭祀必祝之，祝曰：‘必勿使反^⑥。’岂非计久长有子孙相继为王也哉？”太后曰：“然。”

       左师公曰：“今三世以前，至于赵之为赵，赵王之子孙侯者，其继有在者乎？”曰：“无有。”曰：“微^⑦独赵，诸侯有在者乎？”曰：“老妇不闻也。”“此其近者祸及身，远者及其子孙，岂人主之子孙则必不善哉？位尊而无功，奉厚而无劳，而挟重器^⑧多也。今媪尊长安君之位，而封之以膏腴之地，多予之重器，而不及今令有功于国，一旦山陵崩^⑨，长安君何以自托于赵？老臣以媪为长安君计短也。故以为其爱不若燕后。”太后曰：“诺。恣君之所使之。”

       于是为长安君约车百乘，质于齐。齐兵乃出。

      【注释】①郄（xì）：同隙。有所郄，是身体有所不正常的委婉说法。②耆（shì）：通“嗜”。③贱息：对自己儿子的谦称。④黑衣：赵国侍卫所穿的衣服，用以指代宫廷卫士。⑤没死：冒死。臣对君的谦卑用语。⑥反：同“返”。古代诸侯嫁女于他国为后，若非失宠被废、夫死无子或亡国失位，是不回国的。⑦微：非。⑧重器：指金玉珍宝。⑨山陵：喻帝王，此处指赵太后。崩：喻帝王死。

    With over 300 years of history, Harvard University, US, welcomed its first-ever Chinese commencement(毕业典礼) speaker. On May 26, He Jiang, a 2016 PhD（博士学位）graduate, gave a speech that stood for the graduate students at commencement. It's one of the highest honors for a Harvard graduate.

    In his speech, he told a story about his childhood. He grew up in a poor village in Hunan. Once a spider bit him on the hand, and his mother had to set his hand on fire to cure him. There were no doctors in the village, and this was the only cure a rural woman knew.

    When he got older, he couldn't help but think about why there wasn't a better cure at that time. And he thought out the answer ---- the unequal distribution of knowledge in the world.

     “Even today we haven't been very successful in bringing knowledge to where it's needed most,” said He. “Even basic life-saving knowledge we can get easily in the modern world is often unavailable in poor areas.” According to the China Children and Teenagers Foundation, there are still around 3 million children in China lacking education, and most of them live in rural areas.

     “One of the biggest problems for rural students is that they lack chances as well as motivation(积极性). It disturbs me that many people in rural areas think studying is useless.” Said He.

    But He Jiang knows how education can change people's lives. “I just hope my experience can give those rural students a bit of encouragement and hope,” said He.
