The secret of tea was a closely guarded secret in the Middle Kingdom. Botanist Robert Fortune traveled through Guangdong, Zhuzhong, and Fudian provinces to study the secret of tea. He discovered that these effects were made with a type of paint, known as Prussian blue, iron ferocyanide,. The taxonomy changed from Camellia bohrei and Camelliabohrei into Camellia sinensis, tea from China.
