《宋史·列传·卷二百二十七》
派大将刘法攻取朔方，刘法认为不行，童贯逼他说： 你在京城时，亲自领命，说一定能成功，现在认为难以成功，为什么？ 刘法不得已出塞，遇敌伏击而死。
遣大将刘法取朔方，法不可，贯逼之曰： 君在京师时，亲授命于王所，自言必成功，今难之，何也？ 法不得已出塞，遇伏而死。
He sent a great general, Liu Fa, to capture Shuofang. Liu Fa thought it would not work, but Tong Guan pressured him by saying, "When you were in the capital, you accepted the order and said that you would definitely succeed. Now you think it will be difficult to achieve it. Why?" Liu Fa had no option but to go out of the country, faced an enemy ambush and died.
