长江里有白鳍豚

In the early 1970s, the fisherman's child Chang Xing first went with his parents for fishing in the Changjiang River and saw a shoal of lipotes vexillifers. He was immediately fascinated by this lovely animal and since then has established an indissoluble bound with lipotes vexillifer. Later Chang Xing knew a young science researcher of the factory's aquatic life institute (the author Luo Ming) by chance. For the coming several decades of years, for the same goal, the two people have been paying attention to and protecting lipotes vexillifers. However, the extinction of the lipotes vexillifer was inevitable. In the summer of 2016, Chang Xing met a group of children participating in the summer camp along the Changjiang River, who want to see the lipotes vexillifer.
