Better Check 1st!!

This post maybe pointless but i feel terrible for been posting anything...
Before going to a place to play or for business...plz check the culture of the place first!!

一家卖酒的angmo公司，想要把自己的酒拿到中国去卖，so the company brought some of the beer and went to Bei Jing. Besides promoting their beer they also brought caps with them to be given out free!! So they prepared their stuff and set up a stall...
One the first day there were no customers at all...hmmm...so the managers wondered but did not give up..then on the second day..the same thing happen...no one even stop by...even the free caps din work!!! *and they thought Chinese 贪小便宜*...
So after a week of failure they gave up...and went back to their home country...they held a meeting and started to discuss what cause this failure...in the end they still had no conclusion..
So they invited a Chinese employee in the company to try the beer and ask for his opinion...
Manager:" So what do you think of the beer?"
Chinese employee:" Great!! Better than the ones back home“
Manager:" Hmm...if it is better than the ones back at ur home, why did no one even want to take a look at it, we even gave out free caps!!?"
C.E. :"Hmm...I'm not sure..can u tell me what colour is the cap..as mayb the colour is not a lucky colour for Chinese."
Manager:"Green."



Do you guys understand??

Green cap...绿帽...
