The upper reaches of the Jinsha River at Yeba Beach hydropower station extracts more than 38 meters of concrete core samples.

On May 11, the YeBaTan Hydropower Station, the largest hydropower station in the upstream section of the Jinsha River in the Sichuan-Tibet section, successfully extracted a 38.10-meter-long concrete core sample, equivalent to the height of a 12-story building, breaking the record for extracting core samples from similar dams in China.
