《太平广记·卷一百四十六·定数一》
这时太宗得了痢疾很痛苦，很多大夫治了都不见效。就下诏书访问殿庭中的左右大臣，有能治这种病的，一定重重赏他。
时太宗苦于气痢，众医不效，即下诏问殿庭左右，有能治此疾者，当重赏之。
At this time, Taizong suffered from dysentery and was in great pain. Many doctors treated him but to no avail. So he issued an edict to ask the ministers of the left and right in the palace. Anyone who could cure this disease would be rewarded heavily.
