They were to find that this dreadful woman was a dangerous foe to oppose. Among the potentates was Tao Wang, Prince of Tsi, who, after doing homage to the young emperor, was invited to feast with him. At this banquet Liuchi made her appearance, and when the wine was passed she insisted on being served first. These unpardonable breaches of etiquette--which they were in the Chinese code of good manners--were looked upon with astonishment by the visiting prince, who made no effort to conceal his displeasure on seeing any one attempt to drink before the emperor. Liuchi, perceiving that she had made an enemy by her act, at once resolved to remove him from her path, with the relentless and terrible decision with which she had disposed of her former rivals. Covertly dropping the poison, which she seems to have always had ready for use, into a goblet of wine, she presented it to the prince of Tsi, asking him to pledge her in a draught. The unsuspicious guest took the goblet from her hand, without a dream of what the courtesy meant. Fortunately for him, the emperor, who distrusted his mother too deeply to leave her unobserved, had seen her secret act and knew too well what it meant. Snatching the fatal bowl from the prince's hand, he begged permission to pledge his health in that wine, and, with his eyes fixed meaningly on his mother's face, lifted it in turn to his royal lips. The startled woman had viewed the act with wide eyes and trembling limbs. Seeing her son apparently on the point of drinking, an involuntary cry of warning burst from her, and, springing hastily to her feet, she snatched the fatal cup from his hand and dashed it to the floor. The secret was revealed. The prince of Tsi had been on the very point of death. With an exclamation of horror, and a keen invective addressed to the murderess, he rushed from that perilous room, and very probably was not long in hastening from a city which held so powerful and unscrupulous a foe. The Chinese Borgia's next act of violence found a barbarian for its victim. The Tartar chief Mehe sent an envoy to the capital of China, with a message which aroused the anger of the empress, who at once ordered him to be executed, heedless of the fact that she thus brought the nation to the brink of war. Four years afterwards Hoeiti, the emperor, died, leaving vacant the throne which he had so feebly filled. It is not to be supposed that Liuchi had any hand in this closing of a brief and uneventful reign. Her son was in no sense in her way, and served as a useful shield behind which she held the reins of government. But she was in no haste to fill the vacant throne, preferring to rule openly as the supreme power in the realm. In order to consolidate her strength, she placed her brothers and near relations in the great posts of the empire, and strengthened her position by every means fair and foul.
