A citizen in Shanghai burnt more than 3,000 yuan (£340) banknotes in a microwave as she tried to disinfect them.
The bizarre video shows a bank employee counting the burnt cash and exchanging it for new notes for the woman named Yu.
According to reports, Yu heard that cash can carry coronavirus particles and can be put in the microwave to be disinfected.
Since the banknotes were damaged seriously, the bank can only exchange around 1000 yuan (£112).
