This paper is intended to advocate the use of Cha-Ma Ancient Route elements in the packaging design of exported tea, promote Chinese culture and tea ceremony spirit to widely spread along with exported tea, improve the cultural added value of exported tea products and further expand the tea export market using Chinese character style design of alphabetic characters. It is proved by analysis that the use of Cha-Ma Ancient Route element on the package of exported tea plays a representative role in expression of Chinese culture and tea ceremony spirit. By reflecting on the shortcomings and difficulties in exported tea packaging in the present stage, it is proved that the Chinese character style design of alphabetic characters is of great significance in the design of exported tea packaging. By analyzing the differences between Chinese and Western characters, this paper summarizes the ideas and methods of Chinese character style design of alphabetic characters. The feasibility of Chinese character style design of alphabetic characters is cleared by an example. In order to make the elements of Cha-Ma Ancient Route more effective in communication and empathy, attention should be paid to the Chinese character style design of alphabetic characters. The proper use of the Chinese character style design of alphabetic characters can effectively avoid the similarity of the packaging design of exported tea to western beverage packaging design in this stage. To further improve China's international influence and enhance the international competitiveness of China's exported tea, it is a feasible method to properly use the Cha-Ma Route element, a representative of Chinese tea culture, in the packaging of exported tea. The unification of the form and content of export tea packaging design via the Chinese character style design of alphabetic characters will help to spread Chinese culture and the spirit of Chinese tea ceremony, and will promote the international influence of Chinese tea culture on a deeper cultural level.
