This year's performance aims to be more vivid and lively, with greater emphasis on improvisation and "letting people from various professions and walks of life tell their own unique stories", he said.
For example, some formations will focus on farmers, factory workers, students, delivery workers and others. "We want our performers to display genuine emotions and voice their true feelings for the motherland."
At 8 pm on Tuesday, China will host a grand evening gala at Tian'anmen Square with theme performances, shows and fireworks, lasting around 90 minutes, said Pang Wei, executive deputy minister of the gala's organization department.
The theme performances are in four sections, including Ode to the Red Flag, We Walk on the Great Road, On the Field of Hope and Lead the New Era. Around 3,290 people will participate in the performance, which aims to present China's rise, she said.
The featured show also has four parts: The Great People and Their Magnificent Homeland, Jubilant People and Beautiful Landscape, New Era in a Brand-New World and Shared Happiness and Common Aspirations. Around 3,650 people will showcase unique cultural heritages from all around China, and up to 40 classic and beloved songs will be performed.
Xiong Zhuo, executive manager for volunteers, said more than 160,000 volunteers have joined to assist the nation's celebration, 10,000 of which are directly involved in the parade and the grand evening gala.
Most of the parade volunteers are young people aged 19 to 30, including many celebrities and influencers. "The smile of volunteers is the best business card for Beijing," Xiong said.
Huang Cheng, a representative of the volunteers, said she and other volunteers have been drilled extensively and are ready to help in the national celebration.
"We are very honored to be volunteering for this historic event," she said. "Although each of us is only responsible for a small task, it still constitutes a contribution to the overall success and glory of the nation, so all volunteers have been diligent and willing to do our jobs."
