Recently, the TV drama "Meng Hua Lu" has become a popular show, which has become a phenomenal ancient costume idol drama with both broadcast volume and discussion degree. The rapid popularity of "Meng Hua Lu" seems unexpected, but in fact it has its inevitability. This is the respect for the audience's aesthetics and cognition. In recent years, many ancient costume idol dramas have followed the production mode of "traffic actor + big IP", and firmly controlled the traffic password in a seemingly fast and secure way. Ancient costume idol drama is a type of drama with high requirements for appearance, and the casting based on the flow standard makes some male and female protagonists lack even satisfactory appearance conditions, let alone acting skills. Under the production mode of assembly line, some ancient costume idol dramas deviate from the pursuit of quality and aim to create topics and members to pull new ones. In art, there are many problems, such as the distortion of filter application, single role modeling, routine plot, etc., which exacerbate the boredom and dissatisfaction of the audience. In this background of "ugly puppets" in power, the audience's requirements for costume idol dramas are first of all their respect for their own aesthetics. It is undeniable that the high appearance of the protagonist and the pleasing picture are the important driving force for the audience to pursue the drama. "East Palace", "under the Royal Guards" and "fragrant honey sinks like frost" are all related to this. "Meng Hua Lu" goes to a higher level. The character's neat bun and elegant makeup not only match the character, but also appear fresh and refined. As far as the picture is concerned, no matter the Jiangnan style of small bridges and flowing water, or the noisy and bustling Tokyo marketplace in the Northern Song Dynasty, it does not lose the natural and flexible beauty. Respect for audience aesthetics also means innovation in artistic form and content expression. Aesthetic fatigue caused by homogenization is a major reason why ancient costume idol dramas have been criticized. Some well-known dramas are also unavoidable, such as the costume modeling, environmental scenes, character setting and plot development of Chen Xiyuan, which is considered to be highly similar to the peach blossom of three lives and three generations. The reason why "Menghua Lu" can be recognized by the audience is to find a new way to jump out of the mysterious drama and the Qing palace drama, set the story background in the Northern Song Dynasty, and bring the audience a surprising harvest with rich historical knowledge and profound cultural connotation. The plot is based on the historical background of the Tianxi party struggle and the musical system, and skillfully integrates the local customs of tea operas, Cuju, etc. to restore the life picture of the song people with a smoke and fire flavor with details such as clothing, utensils, food, etc. The textual research and Discussion on history and culture caused by this, in turn, increased the popularity of the Menghua record. The respect for the audience's cognition is mainly reflected in the solid plot, plump characters and values that meet the expectations of the audience. This is the core competitiveness of film and television works, and also the weakness of many ancient costume idol dramas. In 2022, the play "mirror · two cities", adapted by IP, lacked connotation and became a thin "classic" love story. In contrast, "Meng Hua Lu" is much more thoughtful. In addition to the plot of the Yuan drama "Zhao Pan'er saves the wind and the moon", the play depicts the process of the hero and the heroine growing up in love after encountering and helping each other. At the same time, it tells the story of three women with low status who, after their marriage and love were frustrated, worked together to build a small tea house into a big restaurant step by step. Such plot setting is not only in line with the audience's expectations for the types of ancient costume idol dramas, but also in line with the life and emotional experience of contemporary women. It meets their general psychology of longing for economic and spiritual independence, and reflects their respect for the laws of art and their accurate grasp of social emotions. Whether it is praise or criticism, there is expectation for good works behind it. The popularity of "Meng Hua Lu" is just another verification of a simple truth: respecting the audience, the law and common sense is the real "traffic code", which is also the original intention of domestic dramas, including ancient costume idol dramas, that need to be picked up again. We look forward to more sincere and high-quality dramas, so as to improve the overall level of domestic dramas. (outlook new era)
