On the second day, the research group opened their research activities on the theme of "Feeling the East River Water · Exploring the source of three hundred Mountains". Arriving at the three Hundred Mountain scenic spot to the conservation stone, after listening to the narrator's explanation of the Dongjiangyuan and the introduction of the Dongshen water supply project, the opening ceremony of the theme research activity was held, and the Hong Kong teenagers collectively read the "Young China said" and finally took a group photo.

After the opening ceremony, the Hong Kong research group went to the Siyuan Exhibition Hall, which showed the love and protection of Anyuan people for decades. The five chapters of the exhibition hall with the theme of "water" inspire the students to take the protection of the source of the Dongjiang River as their own responsibility, strengthen the awareness of ecological civilization, strengthen the action consciousness of love and protection of the source, and forever secure the reputation of "Dongjiang Jade". Three Hundred Mountains has always adhered to ecological priority and green development, and practiced the concept of "two mountains" as the core soul of three hundred Mountains national 5A tourist attractions.

This study activity won praise and blessings from Hong Kong students. I hope that through this activity, they can also gain full, continuous progress, and dreams come true.
