just a small market gossip if I may. I was in the shop of one not really famous tea factory for cuppa tea & chat. They just came back from Shenzhen Tea Expo. Well , woman told me that their company spent 300 000 CNY ( 42 862 $ ) for those 5 days "fun" . So this is the one part of expenses what big companies have and of course it reflects in prices of their products along with other marketing tools and running premises of their business.
I can imagine how much spend DaYi or Zhong Cha with Rong Shi who always have a hot spot on those Expos.
