The sound waves surge, start the microphone immediately | PLA helps JD 618 Happy Night

At 19:30 on June 17, 2025, Jingdong 618 Happy Night, a grand feast integrating music, entertainment, shopping and carnival, was launched at the same time on Hunan Satellite TV, Mango TV and Jingdong APP. This annual grand ceremony with the theme of "Happy delivery in the middle of the year" gathered more than 50 stars such as Na Ying, Zhou Shen, Zhang Yixing and Wu Xuanyi, and combined top audio-visual performances, immersive interaction and billion yuan welfare to present a summer carnival of "shopping+entertainment" for the national audience.

The evening party innovatively set up "four themed parties", with Da Zhangwei, Li Sheng, Yang Di, and Zhang Yuan serving as preparatory officers, leading over 50 celebrities to sing and interact with each other. A medley of Yingjin songs, Zhou Shen's surprise singing and dancing, Zhang Yixing's return as the king of the stage, and exciting performances such as the sisters' lively singing and dancing, campus memory killing, etc. were staged in rotation.

This evening party utilized cutting-edge stage design techniques, with the infinite ring symbol as the base and the number 8 as the core design. Multiple stages and regions were interconnected, combined with cutting-edge technology, to create a "god level scene". Pioneering the jukebox mode, the audience can order songs in real-time and enjoy the joyful atmosphere of the entire choir.

JD 618 Happy Night is not just an entertainment party, but also an innovative attempt to deeply integrate e-commerce and entertainment.

The JD 618 Happy Night has come to an end, but the joy and surprise it brought us are unforgettable. This dual feast of shopping and revelry not only allowed us to enjoy exciting programs, but also allowed us to enjoy the fun of shopping.
