When creating The Longest Day In Chang'an, the director Cao Dun paid great attention to the accurate description of the details of life in the Tang Dynasty, and the use of costumes in the film can be described as meticulous. From generals to soldiers, the armor worn by the team of armor restorer Wen Chenhua is manipulated. Soldiers' helmets and armor are based on the murals in the Tang Dynasty, and the armor of the Dragon and Tiger Army refers to the murals in princess royal's tomb. Then, after the explosion of fire in The Longest Day In Chang'an, how did it build a cultural IP?

First, the implantation of food culture

The story takes place in the third year of Tianbao, and reproduces the food culture of the Tang Dynasty more than 1,111 years ago based on the local perspective. In the play, the basin mutton and fire crystal persimmon cake are the epitome of local cuisine in Xi 'an today. At the beginning of the plot, "Hu cake" appeared twice, the first time in the cake stall of Chang 'an market vendor, and the second time in the mourning hall where Cui Qi missed his brother. As a common food in Chang 'an in Tang Dynasty, Hu Bing, a western cuisine, shows the trend of Hu Hua in Tang Dynasty. Tea drinking was quite popular in the Tang Dynasty, and the details of tea culture were also remarkable. In the fifth episode, when the prince summoned Li Bi, Li Bi's series of actions, such as suffering and drying, were the unique "tea pickling method" in the Tang Dynasty. When He Jian made tea, the details of "taking things from the pot" were vivid, and historical data were verified. Tea in the Tang Dynasty was also called "tea soup". People in the Tang Dynasty often ground tea into powder and boiled it for drinking. Because the tea soup was bitter, salt, ginger and mint leaves were added to it for seasoning.

Second, restore the ancient buildings in Chang 'an and create a tourism culture with unique regional characteristics

The popularity of The Longest Day In Chang'an has driven the growth of tourism culture in Xi 'an, especially the hot spots related to the Tang Dynasty culture, which has injected new vitality into the cultural tourism in the ancient city. Film and television works should conform to the development of the cultural market in the new era, deeply tap the local consumption potential, create a unique cultural IP, and enhance local cultural self-confidence. The architectural form and house style in the play follow the architectural characteristics of the Tang Dynasty, and highly restore the layout of the 118 squares, the east and west cities and the imperial city of Chang 'an in the Tang Dynasty. On the Shangyuan Festival, the "Flower Calyx Xianghui Building", where saints enjoy lanterns and entertain ministers, reached the peak of architecture in the Tang Dynasty. The "Flower Calyx Xianghui Building" is located in Xingqing Palace and set in Xingqing Ruins Park in Xi 'an, giving the audience a glimpse of the prosperous Tang Dynasty.
