This chapter is the introduction to this book. This chapter begins by explaining the motivation for writing this book and the topics to be discussed. The author starts with details captured from street in London, combined with her life and research in the UK. She realized that the UK’s importation of tea from China in the seventeenth century was one of the earliest global trade, and a key factor in the social transformation of East and West in modern times. The spread of tea not only introduced Chinese lifestyles and designs to Britain but also had a profound impact on British culture and design. It subtly changed the British people’s dietary habits, social manners, and aesthetic tastes, while affecting the development of related industries at the same time. The author believes that the popularization of tea reveals how traditional Chinese lifestyles and designs have blended and influenced British culture. From this, we can see that cultural influence and integration are not unidirectional linear transmissions, but a process of mutual influence and promotion.
