Two young men from northwest China have been arrested for selling fake banknotes worth more than 200,000 yuan (HK$233,000).
The men, both 23, had been sending the counterfeit currency by express delivery, the Chinese Business News reported.
They were found by police with bogus bills of 10 and 20 yuan in their home in a village in Xian, Shaanxi province.
The report said the men started forging the notes in May and earned 10,000 yuan for every 100,000 yuan of fake notes.
A deliveryman became suspicious and notified the police, who found bundles of bogus bills, all with the same numbers, packaged to be sent to five cities.
Watermarks and silver threads had been added to the notes, which had also been “aged” to look more realistic, police said.
