It is said that the "Long River" in "Three thousands of feet" is the artificial waterfall of the POS machine of UnionPay poetry. Is it true?/You don't say.

Yes, Three thousands of feet was indeed filmed here. This artificial waterfall is no ordinary waterfall. The so-called poetry POS charity is actually the charity action of "China UnionPay Poetry POS" initiated by China UnionPay and China Soong Ching Ling Foundation in Zhangjiajie, Hunan Province in 2020, which is used to build a public welfare library and offer artistic literacy education courses for children in mountainous areas. During the activity, a huge waterfall "cloth" flew down in the mountains and deep valleys. A closer look reveals that it is not a wave, but a poem, a masterpiece of mountain children, and a real long river of poetry.
