Lucky charm Taiwan has a packaged cookie called "Kuai Kuai". For some company, It not just only a snack, but a lucky charm. You could find some "Kuai Kuai" in their server room, even in the TSMC (Taiwan Semiconductor Manufacturing Company, Limited), hoping their service machine will not malfunction. Reportedly, this ritual originated in the TSMC. Although, I am usually not a superstitious person, but I have tried it. Our service machine was usually crashed. One day, I replaced the server with a new one and put some "Kuai Kuai" in our server room. Initially It seemed to work! Until one day, some mice were polished off the cookies, but our server still working until now! In my case, we only needed to replace a new machine, and the lucky charm was useless for me.
