The Chinese are tea drinkers. Everywhere you go in China you will see people carrying jars of tea - literally their old recycled glass jars with lids! And the tea can be green or brown or even red! Often is has bits and pieces floating in it - flowers and roots, leaves and stems.
One of the popular teas which is said to relieve head aches is Chrysanthemum tea. In these pics you can see the tea growing in the terraces on the side of the mountain. At the time we visited they were harvesting yellow and white flowers. the people work incredibly hard bent over all day with huge packs on their backs, but they still had a ready smile and a wave for us.
