In which episode of Lurking Late Autumn did he die?

Died late in episode 19. Cuiping fell ill and sent her to the hospital for examination in late autumn. While taking good care of Cuiping, Wan Qiu expressed her true love for Yu Zecheng. Cuiping was so angry that she burst into tears.

Yu Zecheng could only try his best to deal with the two women. Wang Zhanjin, the landlord from Cuiping's hometown, moved to Tianjin and recognized Cuiping on the street. Yu Zecheng believed that this person must leave Tianjin immediately. He asked the gang leader Long Er, who had been favored by him, to secretly handle the matter.

In late autumn, she went to the hospital to get Cuiping's test report. She was surprised to find that Cuiping was still intact. After asking Wang Zhanjin to find out the situation, she finally saw through the fake identities of Yu Zecheng and Cuiping. Yu Zecheng could not make up his mind to kill Wanqiu and silence him. In order to get Yu Zecheng, Wanqiu was willing to keep this secret for him.

Latent plot

The organization asked him to stay in the military command and lurk on standby. Yu Zecheng, codenamed Emei Feng, was ordered to the Tianjin spy station of the military command. The station chief Wu Jingzhong asked him to bring his wife. The party organization sent him Cuiping, a female guerrilla captain who is generous, simple, fierce and upright.

Let the two become a fake couple. Cuiping, who had practiced kung fu and was an expert in marksmanship, could not adapt to the life of an official wife who ate Western food and played mahjong. She made many jokes and strongly asked to leave many times. The two also had constant conflicts in the details of their lives and personalities.

In January 1946, the Kuomintang and the Communist Party began "military adjustments." Yu Zecheng discovered that Zuo Lan was among the military transfer personnel sent by the Communist Party of China. General Yu Zecheng handed Zuo Lan the list of surveillance agents arranged around the representatives of the Communist Party of China, and made it public, and the first battle was won.
