My boss is a taiwanese tea lover and every day he makes green tea from tea leaves. We often serve service teas everyday when a costumer asks for it but only from herbs in a tea bags that we bought from a supermarkets.
My boss tea collections do not service their green tea because its for them to drink. What i always heard from them is that it is very expensive that 
every packs of these is equivalent to P1900. according to my boss..
When i asked him(myboss) , about the origin of tea, they told me that, one day the emperor of a chinese dynasty boiled a hot water and suddenly a leaf from the famous tea plant(camelia sinensis) fell from the pot of water and when it blends, they smell the sweet aroma and they drink it and that is where it started.
And years and years passed by, they cultivated more and more of those tea plant and that is how the production made.
Not only chinese people love to drinks tea because it was spread out to the world and it is one of the most consumable drinks aside from coffee, chocolates, cola, etc.
Because of everyday's routines, when i arrived early in the morning, without their knowlegde i often made tea and i drink it while i am resting there before the working time and sometimes i like it when its cold so i put some of the teadrinks i made in a fridge to chill.
This is the tea leaves they always made 
,and i dont know how they mafe it that little but when you are a tea lover you would always compare the difference of its delicious taste than a tea made from a cheap leaves that we usually saw displayed in a grocery stores.
And this is the tea leaves after you put a hot water because when you put the tiny leaves in a hot water the water starts to soaked from the leaves and then you can smell the sweet aroma from the leaves that starts to open after in 5 mins( minimum time) and the water turns green.
My boss told us that green tea leaves is very good for our health and has many benefits in the body.
