His parents, both older than 60, were able to learn the game quickly and even won a round. Alsemgeest, who has lived in China for more than three years, first played mahjong last summer, when he was on a business trip in Gansu province. A group of Chinese friends invited him to play.

"I thought the game was quite complicated and would take me weeks to learn. I was very surprised that it only took me one evening to learn the basic rules and know how to play it," says Alsemgeest, 34.

Alsemgeest says he initially thought the game was difficult because of the symbols on the tiles. But after learning the basics of the game, he became fascinated with it.

Alsemgeest's mother enjoyed the game so much that she is thinking about joining a mahjong club in her hometown of IJsselstein

The 61-year-old says there are two mahjong clubs in her town: one for the old and one for the young. The former was set up by some Indonesians and has recruited some locals to play. The clubs often hold competitions.

"Maybe I will play it many times in the future. It's a good way to learn and think. Good for my brain," jokes Alsemgeest's mother.

Although Alsemgeest can play mahjong and knows the basics, he says it will take time to master the complicated rules, and remember how many tiles of the same symbols are throw into the well.

For Cheremnikh, the difficult part of the game is the speed at which it's played. When he's playing with Chinese, Cheremnikh says it's hard for him to keep up and bring in a tile and throw one out in a short period of time.

"I'm considering cooperating with owners of mahjong houses in hutong. I want to bring foreigners to the local mahjong houses and let them experience the authentic mahjong culture," he says.
