Nanxian Dihuagu is a folk dance of the Han nationality. There are many forms such as "couplet flower drum", "bamboo horse flower drum" and "surrounding dragon flower drum". Most of them are couplet flower drum with one dan and one clown, three flower drum with two dan and one clown, and four, six and eight flower drum with men and women in pairs. The performance content of Dihuagu is mostly about labor and love life, and there are also songs telling historical stories and characters. The singing of flower drums such as congratulations and blessings is mostly improvisation. Nanxian Dihuagu is mainly spread in Nanxian, Yiyang City, Hunan Province and surrounding areas. Dihuagu in various places is diverse and integrated, with both commonalities and local differences, forming different styles. Nanxian is known as the "Dihuagu Nest". Nanxian Dihuagu is a folk art form created by the people in its territory during labor. In 2006, Nanxian Dihuagu was identified as the first batch of intangible cultural heritage list projects in Hunan Province. Nanxian Dihuagu originated in the third year of Jiaqing in the Qing Dynasty (1796) and evolved on the basis of folk folk songs, minor tunes and labor songs. It is deeply rooted in the people with its simple and rough movements, bright and high-pitched music, lively and free performances, rich life atmosphere and unique artistic style. The Changsha Flower Drum Opera in Hunan was formed and developed on the basis of this kind of flower drum. The enlightenment period of Nanxian Flower Drum was the Duizi Flower Drum. One ugly and one female (both ugly and female are played by men) hold fans and silk, sing and dance together, accompanied by gongs, drums and suona, and have fun in the house and even on the fishing boat. Its development period was during the Jiaqing period of the Qing Dynasty. At that time, circuses were popular in Beihekou and Mulu Lake. Later, they were combined with the Duizi Flower Drum to evolve into a new folk art form, namely the bamboo horse flower drum. During the Daoguang period of the Qing Dynasty, the land was built up in the territory, and immigrants came in droves. The Lantern Festival and the Mid-Autumn Festival were in line with this, which pushed the Nanxian Flower Drum into a prosperous period. After the founding of New China, the celebrations of land reform and the establishment of the cooperative people's commune pushed the flower drum into its heyday. During the ten-year "Cultural Revolution", the Dihuagu was labeled as "feudal, capitalist and revisionist" and entered a period of confinement. Since the reform and opening up, under the impact of economic globalization and modern civilization, the cultural ecology has undergone drastic changes. The traditional intangible cultural heritage has gradually lost its former glory and its endangered status has become increasingly serious. Nanxian Dihuagu mainly has three forms: the Duizi Dihuagu, the Zhuma Dihuagu, and the Weilong Dihuagu. The three types of Dihuagu performances have their own characteristics. The performances include dances that reflect people's working life, the love life between men and women, and the wishes for peace, good weather, and a good harvest. The performance forms are very rich. The Duizi Dihuagu is also called the single flower drum, with two men playing the role of a clown. The clown wears a red headscarf or a straw hat, a hat with a stalk, or a wine stalk as a headdress, wears a set of light blue, yellow, or black clothes, holds a banana fan, a paper fan, or a silk fan as props, and draws three lines of white powder on the eyes and nose, which looks like the word "small", so it is called a small painted face. The female role wears a silk scarf, a handkerchief, a fairy head, a red or yellow ornament on the head, and a set of red colorful clothes and pants or colorful clothes and skirts made of quilts, holding silk woven red silk and wine glasses as props. The two sing and dance, and play "sets" and "nests" according to the lyrics of tunes such as "Looking for a Lover in December", "Drag a Bench", "Seeing My Sister in October", "Picking Tea", "Arranging Flowers", "Fan Tune", and "Sending Wealth Song", especially using fans and handkerchiefs to express the emotions and personalities of the characters. The costumes, singing content, and performance routines of the bamboo horse dihuagu, the clown and the dan, are the same as those of the duizi dihuagu. The added protagonist is a warrior. He wears a red fairy head or a white top hat, wears white or red martial arts clothes, holds a horse whip, and carries bamboo horses of various colors on his shoulders or waist. He interweaves with the clown and the female role of the dihuagu, walks in the shape of "8" (some are accompanied by a horseman who can do somersaults), goes around the "circle", and plays "sets". The scene is majestic and the performance is delicate. The performance routines of the female and the ugly are slightly different from those of the couplets. There is "sending wealth" when entering the door and "saying goodbye to the east" when leaving the door. The dragon head and tail are connected to 11 or 13 dragon handles, and the dance of the ground flower drum is combined with the routines of "playing with pearls", "starting the well", "coiling the pillar", "holding the butterfly", "sleeping arhat", etc., or the words "a bumper harvest" are displayed to create a festive and auspicious atmosphere. When Peng Dehuai, Duan Dechang, He Long and other older generation revolutionaries spread the red flame here, they loved to watch the performance of the ground flower drum the most. As early as the Gutian Conference in 1929, Comrade Mao Zedong advocated that the Red Army soldiers sing the "flower drum tune". There are many tunes of ground flower drum, including: "Looking for my lover in December", "Mopping the stool", "Seeing my sister in October", "Picking tea", "Flower arranging", "Fan tune", "Send wealth song", "Send happiness song", "Flower watching", "Watching lanterns at the fifth watch", "Butterfly song", "Make noise at the fifth watch", "Pregnant in the tenth month", "Send my lover", "Learn words", "Yangque song", "Three invitations song", "Copper coin song", "To all directions", "Song to invite my lover", "Send my lover song", "Cross tune", etc. For example, "Looking for my lover in December" is performed according to the order of months, with one paragraph for each month, and one paragraph for each meaning: Looking for my lover in the first month of the year, welcoming my lover in the flower festival in the second month, sending an umbrella in the Qingming Festival in the third month, farming in the fourth month, my lover and sister make a fuss about the Dragon Boat Festival in the fifth month, my lover and sister express their heartfelt feelings in the sixth month, blessing in the hot summer in the seventh month, reunion in the Mid-Autumn Festival in the eighth month, persuading my lover in the Double Ninth Festival in the ninth month, missing my lover in the cold winter in the tenth month, expressing love with clogs and umbrellas in the eleventh month, and waiting for my lover in the snowy night of the twelfth month. Nanxian Dihuagu plays an important role in the entire Dongting Lake area. The "West Lake Style" of Changsha Huagu Opera was developed on the basis of Nanxian Dihuagu. In other words, Huagu Opera started with Dihuagu. Discovering, rescuing and protecting Nanxian Dihuagu has high academic and practical value.
