王力
Chunyu himself was in trouble, however, in 8 BC. Wang Gen was ill at the time, and there was speculation that Chunyu would succeed him. Wang Gen's nephew Wang Mang (王莽), who also wanted to succeed Wang Gen, obtained information about Chunyu's corruption and reported the information to Wang Gen and Empress Dowager Wang, who became so angry that she had Emperor Cheng expel Chunyu from the imperial court and be returned to his march. Chunyu, before he left the capital, gave his horses and luxurious carts to his cousin Wang Rong (王融)—the son of his uncle Wang Li (王立), with whom he had a running feud. Wang Li, happy with Chunyu's gift, submitted a petition requesting that Chunyu be allowed to remain at the capital—which drew Emperor Cheng's suspicion because he knew of the feud between Wang Li and Chunyu. He ordered Wang Rong be arrested, and Wang Li, in his panic, ordered his son to commit suicide—which in turn caused Emperor Cheng to become even more suspicious. He therefore had Chunyu arrested and interrogated. Chunyu admitted to how he had deceived Empress Xu and received bribes from her, and he was executed. In the end, Emperor Cheng forced Empress Xu to commit suicide.
