Director Lee Jun-ik's new costume film is a sequel to "Huangshanfa" which attracted 3 million people in 2003. It tells the story of how Silla defeated Goguryeo and unified the Korean Peninsula. The Korean Peninsula is in crisis again. Silla, the most far-sighted of the Three Kingdoms, realized that victory requires not only strong military power, but also unremitting learning from advanced civilizations. Therefore, on the one hand, it humbly learned the culture of the prosperous Tang Dynasty, and on the other hand, it actively showed goodwill to the Tang Dynasty, winning a certain space for development. At the same time, Goguryeo was facing a fragmented situation. The powerful minister Yeon Gaesomun died, and the eldest son Nanyang took over, but aroused the dissatisfaction of the second son Nanjian, and the brothers buried the hidden danger of fratricide. In the end, the ruthless hard-line Nanjian took power, forcing Nanyang to leave and had to ask the Tang Dynasty for help. At this time, Silla had formed a joint force with the Tang Dynasty to eradicate Goguryeo. Eight years ago, the unknown soldier who survived "Huangshanfa" was once again involved in the defense of Pyongyang, but unfortunately became a prisoner of Goguryeo. He was quick-witted and constantly slandered his rival Silla. He also accidentally met the heroic female soldier Jiashun, and wrote a humorous romantic story. Although Nanjian fought desperately and tried to save the capital Pyongyang, the situation was over and the history of Goguryeo came to an end. Behind the scenes, the hilarious historical drama that made a comeback was made. Eight years ago, the success of "Huangshanfa" gave the Korean film industry a new revelation that historical history can actually be filmed very well. For a long time, Korean costume movies have been quite similar to Japanese Taiga dramas. They have extremely strict requirements on costumes and lines. Shooting with a serious attitude will inevitably create a dull and obscure feeling. After the release of "Huangshanfa", the audience saw a unique historical drama. On the basis of historical events as the background, the creators added a lot of jokes to enhance the entertainment and attract a large number of young audiences. Take "Huangshanfa" as an example. The scenes of verbal battles, real chess formations, and dialect melees have become classic cases, and people still talk about them. As the sequel to "Huangshanfa", Taobao women's clothing "Pyongyangcheng" still follows the route of funny historical dramas, with the war between the New Tang Coalition (Silla Tang Dynasty) to eliminate Goguryeo as the background. There are both farces of intrigues between big figures and romantic comedies of desperate soldiers. In order to continue to bring the audience hilarious laughter, "Pyongyangcheng" is still filmed in all dialects. In "Huangshanfa", the main story is about the battle between Silla and Baekje, mainly in Jeolla Province and Chungcheong Province dialects. "Pyongyangcheng" also adds the dialect of the Goguryeo region. In addition, the soldiers who participated in the war came from all directions, each speaking their own local dialects, almost speaking all the dialects of the eight provinces in the country, which can be described as a carpet-style dialect war. In addition to the melee in terms of lines, the film also put a lot of effort in arranging the war scenes. Among them, the most eye-catching is the bee shell invented by Goguryeo. The soldiers threw the mysterious weapon containing bees at the enemy, and the bees flew out and created chaos in the enemy camp. In addition, there are so-called bags filled with pig urine, which are also thrown at the enemy camp as a lethal weapon. There is also a unique rice bomb, which is to fill the bag with food, push it to the battlefield with a chariot, and then throw it at the enemy camp. These new weapons made from local materials are full of humor in the era of cold weapons. Although absurd, they are also full of wisdom. Director Li Junyi jokingly called this war an original ecological war, green and environmentally friendly. The old boy and the new face Xian Yushan are heroic. Director Li Junyi has always adhered to his own aesthetics in selecting actors and does not deliberately use big-name stars to attract business. Even the "The King and the Clown" that was popular at home and abroad did not have a first-line actor. Instead, Lee Jun-ki became the most popular after filming this film. This time, Lee Joon-ik used the same basic cast from "The Battle of Huangshan". In addition to Jung Jin-young who played General Kim Yu-shin and Lee Moon-sik who played the unknown soldier, Lee Joon-ik also changed the all-male cast of the previous work and added a female character - Goguryeo female soldier Ga-sun. She had a romantic relationship with the soldier played by Lee Moon-sik in the midst of war, which was quite interesting. The actress who had the honor of becoming this female general was Seon Woo-sun, who had starred in the popular drama "The Queen of Housewives". Lee Joon-ik said that the biggest reason for choosing Seon Woo-sun was that she had an indescribable heroic spirit. After watching too many of them, he was very impressed by their performance.
