I am looking for satellite images over Anduo County, Tibet Autonomous Region, China.

AVHRR： Search at EarthExplorer gives 11577 images in daylight condition, most focus on Indian subcontinent, but should be enough for me. Dates are from 1980 to 2000s.
Declassified Satellite Imagery-1: Low and medium images taken in 1960s, earliest 1961, from CORONA, ARGON and LANYARD satellites. Most are medium to low resolution (15-30 m). A large portion are cloudy. $30 per frame.
Declassified Satellite Imagery-2: Much higher camera resolution at 2 to 4 feet and 20 to 30 feet, from KH-7 and KH-9. Taken in 1964-1965 and 1973. Large swath, relatively lower cloud mask. $30 per frame.
EO-1: no images.
Landsat 1-5 MSS: From 1972 to 1992. Some scan line can be seen. Less cloud. $200 per frame.
Landsat 4-5 TM: July 1982 to Present. Good resolution, less cloud. $425 per frame.
Landsat 7 ETM+ International Ground Stations: No reviews available. No uniform price.
Landsat 7 ETM+: From 1999 to 2003, some are a bit cloudy. Most are usable. $475-600 per frame.
Landsat 7 ETH+ SLC-off: More difficult to process and probably data loss. From 2003 to Present. Can be downloaded with ordering. $200-275 per frame. Landsat 7 ETM+ scenes acquired from 5/31/03 - 7/14/03 and 9/3/03 - 9/17/03 are not available.
SPOT: no image from USGS.
