Su Lao-ch'üan, at the age of twenty-seven, at length began to show his energy and devote himself to the study of books. Then, when already past the age, he deeply regretted his delay. You little boys should take thought betimes. Then there was Liang Hao, who at the age of eighty-two, made his replies in the great hall, and came out first among many scholars; thus late he had succeeded, all men pronounced him a prodigy. You little boys should make up your minds to work. Jung, at eight years of age, could compose poetry. Pi, at seven years of age, could make an epigram on wei-ch'i. These youths were quick of apprehension, and people declared them to be prodigies. You young learners ought to imitate them. Ts'ai Wên-chi was able to judge from the sound of a lute. Hsieh Tao-yün was able to compose verses. They were only girls, yet they were quick and clever. You boys ought to rouse yourselves.
