Mid 1960s through late 1970s Chinese Jiao small denomination notes - but I cannot be sure with the fuzzy images, they might also be rice coupons from food rationing there.
They are Chinese ration coupons: 1) "Henan Province Wheat Flour and Rice Coupon", 2 kilograms 2) "Henan Province Wheat Flour and Rice Coupon", 0.5 jin 3) "Xining Municipal Flour Coupon", 1 municipal ounce 4) "Qinghai Province Local Grain Coupon", 0.5 jin Unfortunately, the images are too blurred for me to read the dates.
