Here is the article in English:

CGTN

"The landing operation is expected in three days."

"The sampling work and the take-off of the ascender from the lunar surface need to be completed within 48 hours ..."

Repost of an old image of the landing site. The base is LRO images and Clementine false colour. the strip without colour is missing Clementine data (a few small patches of missing data elsewhere have been patched by cloning for aesthetic effect). The blue unit is the young basalt thought to be the most likely target. Mons Rumker at centre is red-brown like the highlands suggesting it is covered with a veneer of ejecta from surrounding large craters including possibly the Iridum crater.
