we have identified six samples of candidates with G 10°. By cross-matching with results derived from medium-resolution (R ~ 1800) from LAMOST DR8, we establish that the success rate for identifying VMP stars is 60.1% for the Gold sample, 39.2% for the Silver GW sample, 41.3 % for the Silver GK sample, 15.4 % for the Bronze G sample, 31.7 % for the Bronze WK sample, and 16.6 % for the Low b sample, respectively. An additional strict cut on the quality parameter RUWE < 1.1 can further increase the success rate of the Silver GW, Silver GK, and Bronze G samples to 46.9 %, 51.6 %, and 29.3 %, respectively.
