我们走在大路上

Set against the backdrop of the construction of the Hong Kong–Zhuhai–Macau Bridge—one of China’s major infrastructure projects—and the joint hosting of the 15th National Games by the Guangdong–Hong Kong–Macau Greater Bay Area, the film follows the journey home of a Chinese white dolphin named "Zhuzhu." Through the eyes of the film crew and researchers tracking its migratory path, the documentary portrays the journey of this rare species, which was forced to temporarily leave its habitat due to the bridge's construction and, after many hardships and twists and turns, managed to return to its old home.

The autumn wind blew bleakly, and the wild geese cried out in the chill. On October 16, 1934, the usually deserted wharf on the Yudu River in Jiangxi suddenly bustled with activity. Columns of Red Army soldiers arrived with hurried footsteps, assembling at the site. Entrusted by Zhou Enlai, an ailing Mao Zedong directed the construction of a bridge while lying on a stretcher; the floating bridge was constructed entirely from door planks donated by the local civilians. Over 800 boats from across Yudu County were also gathered at the riverbank. To avoid detection by the enemy, the Red Army assembled the floating bridges to cross the river each night and dismantled them the following dawn. Neither the soldiers nor the officers knew their destination, let alone considered when they might counterattack or rejoin other forces; they simply moved with the troops. And so, the Long March began. (Translated from the Chinese language overview on TMDB)
