Aerial photo taken on July 9, 2020 shows water gushing out from a gate of the Lijiaxia Hydropower Station at the border of Jainca County and Hualong County in northwest China's Qinghai Province. Due to the increasing amount of water inflow volume from the upper reaches of the Yellow River, the Lijiaxia Hydropower Station started to open the gate to release water from June 18 as a way to prepare for the flood peak.
