The latter of these interpretations being obviously incomplete, Chu Hsi adds a gloss to the effect that children are therefore in duty bound to take great care of themselves. In the preface to his work on the Four Books as explained by Chu Hsi, published in 1745, Wang Pu-ch‘ing (born 1671) has the following passage:--“Shao Yung tried to explain the Canon of Changes by numbers, and Ch‘êng I by the eternal fitness of things; but Chu Hsi alone was able to pierce through the meaning, and appropriate the thought of the prophets who composed it.” The other best known works of Chu Hsi are a metaphysical treatise containing the essence of his later speculations, and the Little Learning, a handbook for the young. It has been contended by some that the word “little” in the last title refers not to youthful learners, but to the lower plane on which the book is written, as compared with the Great Learning. The following extract, however, seems to point more towards Learning for the Young as the correct rendering of the title:-- “When mounting the wall of a city, do not point with the finger; when on the top, do not call out. “When at a friend’s house, do not persist in asking for anything you may wish to have. When going upstairs, utter a loud ‘Ahem!’ If you see two pairs of shoes outside and hear voices, you may go in; but if you hear nothing, remain outside. Do not trample on the shoes of other guests, nor step on the mat spread for food; but pick up your skirts and pass quickly to your allotted place. Do not be in a hurry to arrive, nor in haste to get away. “Do not bother the gods with too many prayers. Do not make allowances for your own shortcomings. Do not seek to know what has not yet come to pass.” Chu Hsi was lucky enough to fall in with a clever portrait painter, a _rara avis_ in China at the present day according to Mr. J. B. Coughtrie, late of Hongkong, who declares that “the style and taste peculiar to the Chinese combine to render a lifelike resemblance impossible, and the completed picture unattractive. The artist lays upon his paper a flat wash of colour to match the complexion of his sitter, and upon this draws a mere map of the features, making no attempt to obtain roundness or relief by depicting light and shadows, and never by any chance conveying the slightest suggestion of animation or expression.” Chu Hsi gave the artist a glowing testimonial, in which he states that the latter not merely portrays the features, but “catches the very expression, and reproduces, as it were, the inmost mind of his model.” He then adds the following personal tit-bit:--
