1 Shi Liang - Cooking Oil Stamp Shandong Province

China's Cultural Revolution administration operated a parallel rationing economy alongside the cash currency system, and cooking oil was among the most tightly controlled commodities. Provincial revolutionary committees issued these stamps in denominations measured by weight — "shi liang" being a traditional Chinese unit equal to roughly 50 grams — rather than by monetary value, meaning they functioned as direct commodity claims, not purchasing tokens.

Shandong Province was a major soybean and peanut oil producer, which gave its ration stamps practical weight beyond their face claim. The 1969 date places this squarely within the most chaotic phase of the Cultural Revolution, when central administrative structures had largely collapsed and provincial committees held unusual autonomous authority over everyday distribution.
