Our founder, Rongkang Chen thought that packaging was important for daily necessities, like people need to wear clothes. We could see packaging in everyday life. So he found two other young men to start the manufacture of plastic packaging bag and set up "THREESTONE" in 1997.
We passionately believe that food and wine hold the power to forge lasting connections, setting the table for a life well lived. We invite you to join us for an experience filled with memorable moments built upon food, wine, and friendship. Cheers!
