Footage has emerged from China of a waterfall that apparently came "back to life" after being dried up for more than half a century. <br /><br />The video, filmed in Taizhou, Zhejiang Province on May 18, shows water gushing down the 285-metre-high cliff face. <br /><br />According to local reports, it dried up in the 1950s after a dam was built to conserve water.
