Storyline: Tidal bore tourism surges in east China's Haining City [Voice_over] Villages in Haining City, of east China's Zhejiang Province, are riding a wave of tourism related to the region's famous tidal bore. The Qiantang River tidal bore, the world's largest, is a natural phenomenon that normally reaches its peak during the 18th day of the eighth lunar month, which fell between October 8th and 9th this year. Tidal bores occur when the gravitational pull of the moon and sun creates a large incoming tide that travels into the mouth of a river. A massive wave is sent upstream against the river's current and creates a spectacular visual and audio display. Most people view the wave by standing along the river's coastline, but some soar above it while paragliding, which has become a popular way to participate in the annual event. [Sound_bite] Jiang Kai, coach, paraglider base: "When the tide comes in, our tourist numbers surge, particularly from Shanghai and Hangzhou. During peak times, we can handle around 200 flights daily. It's not just our flying base that attracts more visitors; many nearby water activities also experience a surge in tourists." [Voice_over] Elsewhere, a charming riverside cafe has sprung up for tidal-wave viewing. [Sound_bite] Zhao Mengyi, Tourist: "It's very beautiful here. Sitting here puts me in a very relaxed state, and I feel so close to nature." [Voice_over] Also known as the "Silver Dragon," the Qiantang River tidal bore can reach up to nine meters high and travel at upwards of 40 kilometers per hour.
