You might want to put your beer down for this.

A small factory in China was found making counterfeit cans of Budweiser beer.

It was raided by authorities in Dongguan, a city in Guangzhou, south China, early this month.

Footage from the factory has emerged since, and has started going viral. It's not hard to see why; in the clips, workers dunk used cans into a tub of beer with their bare hands to fill them up:

The filled cans are then sent down a conveyor belt to get sealed:

According to local reports, the factory was churning out 600,000 cartons of fake beer a month, although it hasn't been specified how long it was operating.

The fake beer was allegedly distributed to bars and nightclubs.

A Budweiser representative told Hong Kong-based Ming Pao that the company had reported the matter to the police, and is seeking legal action. Anheuser-Busch InBev, which owns Budweiser, has 14 breweries in China, and is the third-largest beer brand in the country.

The representative added that it has not franchised its operations to a third party.

Weibo users cracked jokes about the video, in response:

"Some ice-cold Budweiser should help you stop worrying [about counterfeits]."

"No wonder when I drank beer for the first time at a karaoke lounge, I didn't feel a thing."

"I definitely can't get drunk on this beer!"

This isn't the first time a fake Budweiser production center has been raided in China — in September last year, police seized nearly 26,000 cans of fake Budweiser in Guangzhou, south China, as well as 36,000 aluminium cans, 20,000 lids and 12,000 pieces of ready-to-use packaging material.
