20 Yuan - Teller Practice Banknote

Teller training notes issued by the People's Bank of China were produced for internal bank staff instruction — specifically for cashiers learning to handle, count, and verify currency without putting genuine notes into circulation. The 20 Yuan denomination is a practical choice for this purpose, as it sits between the high-traffic 10 and 100 Yuan notes that new tellers encounter most frequently.

These pieces were never intended to leave bank premises. Most were destroyed after training cycles ended, which makes surviving examples genuinely uncommon despite their mundane institutional origin.
