2000 Yuan Bank of Pei Hai

The Bank of Pei Hai (Beihai Bank) was established in 1938 in the Shandong base areas under Communist Party control, making it one of the longer-lived regional wartime banks of the civil conflict period. By 1948, the consolidation of Communist-controlled currency zones was already underway — the People's Bank of China was founded in December of that year, and Beihai Bank notes were gradually withdrawn and converted into the new renminbi at fixed rates.

The "S" prefix in the Pick reference signals regional or provisional status, though by this late date the bank's notes were functioning as the de facto currency across substantial liberated territory in northern China. High-denomination issues like this 2000 Yuan reflect the inflationary pressure that plagued all Chinese currencies in the final years of the civil war.
