At length, when the Emperor's beloved son died from the effects of opium in the imperial palace, then the grief of the Emperor, and the conviction of the misery produced by the drug, worked upon his feelings fully as much as upon his judgment. An attempt was made to place the question upon _moral_ grounds; and the Emperor affected on a sudden to weep for the misfortunes of the nation, and to lament the depravity of his "dear children;" and his paternal heart, in the exuberance of its benignity, determined to cut off all their heads, if they would not mend their ways. Thus, by degrees, the reformation of morals became the subject of agitation quite as much as the principles of trade had been before. By this time, the influence of the Empress had quite declined. She forgot that in making many friends she had made many influential enemies. Neither her beauty nor her talents could save her, and she fell rapidly from her pinnacle of power. She only lived to share the Emperor's throne for about five or six years; a very short but remarkable reign. She could not survive the loss of her power; and when her opponents so completely recovered theirs, her proud spirit sunk under the weight which pressed upon her. Nothing could be more touching than the expressions of the Emperor, published in the Pekin Gazette. He calls her a perfect pattern of "filial piety;" and therefore bestows upon her the posthumous title of the "perfectibility of filial obedience." It should be here remarked, that what they call "filial piety" is the highest moral attribute in the Chinese system of ethics. The Empress died in the beginning of 1840, and was buried with great pomp; the whole nation was ordered to go into mourning for a month, and the public officers were not to shave their heads for one hundred days, as a mark of their sorrow. Her death left the Emperor Taou-kwang surrounded by troubles and dangers in his old age, with few about him whom he could trust, and none to comfort him in his difficulties. She left two or three young children. But he had six children by his former wife, of whom nearly all, or, it is believed, more than half have died.
