The question is asking if the Kunlun District reservoir is still under construction.
According to recent updates, it appears that the Kunlun Reservoir project in Beijing’s Changping District (昆都仑区) has made progress and is expected to be completed by 2025. However, please note that this information might change over time, and I recommend verifying with reliable sources for the latest status.
In summary, based on available data as of now, it seems that the construction work at Kunlun Reservoir is ongoing but should conclude within a few years.
