The reigning emperor of the Tang Dynasty sent for Chang Kung, to inquire the secret of such wonderful harmony, and calling for a pen, he is said to have written the character denoting "Forbearance" a great number of times. According to tradition the picture of this patriarch was placed in every dwelling as a stimulus to the imitation of his example, a purpose for which it unfortunately proves quite inert. That the dwellings of the Chinese are cold in winter, hot in summer, and smoky all the year round is inevitable. Even in the coldest weather there is no escape from the bitter cold, except as it may be got by curling upon the _k'ang_. For this reason Chinese women often speak of the _k'ang_ as like an "own mother." A room in which there is none is considered almost uninhabitable. But from an Occidental point of view they are models of discomfort. The heat is but slowly diffused, and during a long night one may be alternately drenched with perspiration, and then chilled to the bone as the heat diminishes. The adobe bricks of which the _k'ang_ is composed crumble if an uneven pressure is made upon them, so that one often finds the _k'angs_ in an inn full of pitfalls. They are always the lodging places of a multitude of tiny monsters to which the Chinese are too much accustomed to complain. Even when the adobe bricks are broken up in the spring to be pulverized as manure--on account of the creosote--the animal life lodged in the walls is apparently sufficient to restock the universe. It is not surprising that the title-deeds to land are in course of years destroyed or lost, for there is in a Chinese house no proper place in which they may be kept. The only closets are made by leaving out a few bricks from the wall. A small board, resting on two pegs often forms the only book-shelf to be found in the apartments even of men of letters. Doors are locked by passing the link of a chain over a staple in the door-frame above; but Chinese padlocks can generally be picked with a wire, a chop-stick, or even with a dry weed, and afford no real protection. Thieves are always provided with an assortment of keys, and often get in by lifting the doors off the pins which serve as hinges. Nothing is easier than to dig through adobe walls. In some of the rich villages of Shan-hsi house-walls are built quite six feet thick to discourage such penetration.
