The spread of tea abroad: 1. Tea culture originated in China, and tea first spread abroad. According to historical records, China's tea was first introduced to the Korean peninsula. From the end of the 4th century to the beginning of the 5th century (Southern and Northern Dynasties), tea was introduced into Korea (now North Korea and South Korea) from China with Buddhism. By the Tang Dynasty, tea had been planted on the Korean peninsula. "Dong Jian" contains that "When Silla (China) pushed the German king, he sent Tang to make gold, and was given tea seeds by Tang Wenzong, which were planted in Luzhi Mountain." In 828 AD, Kim Dalian, North Korea's envoy to China, brought back tea seeds from China and planted them around Huayan Temple at the foot of Zhiyi Mountain. In the 12 century, Songying Temple and Baolin Temple in South Korea strongly advocated tea drinking, which made tea drinking popular among the people.

2. Chadong was introduced to Japan in the 20th year of Tang Zhenyuan (AD 804), and Japanese monks sought Dharma from Hibido most sincerely. In 805 AD, his teacher returned to China. He brought tea seeds and planted them at the foot of Birui Mountain by the river (in today's Shiga County). This is the earliest record of the spread of tea varieties in China. In the Southern Song Dynasty, Japanese Zen master Rong came to China twice in 1 168 and 1 187, respectively, to study Buddhist scriptures and learn tea in China, and to experience the efficacy of tea art and drinking tea in the Song Dynasty. Rong also wrote two volumes of Drinking Tea for Health in Chinese characters. During the Southern Song Dynasty (A.D. 1259), Nanpu, a Japanese monk, showed his knowledge of the Dharma and learned the tea-drinking customs such as Jingshan Tea Banquet and Tea Fighting in Jingshan Temple, bringing back many China tea classics, tea tables and tea ceremony utensils for Jingshan Tea Banquet, and gradually formed Japan's own tea ceremony on this basis.

3. Tea spread south to Indonesia. Indonesia has been in contact with China since the 7th century. 1684, Indonesia began to introduce improved tea varieties from China, and later introduced tea varieties from China, Japan and Assam from India for trial planting. After several ups and downs, it was not until 1826 that Indonesian overseas Chinese introduced tea seeds from China that the foundation of tea industry was really laid. 1827, the sample tea was successfully tried by overseas Chinese in Java for the first time.

4. Tea was introduced to India. India is the country with the largest output and export of black broken tea, and its tea varieties originated from China. 1780, Europeans began to advocate tea planting in India, and the British East India Company sent them to China to plant tea seeds many times, but all failed. 1834, India purchased tea seeds and seedlings from China, planted them in Darjeeling, and invited experts from China for guidance, including the production technology of small-scale black tea. On this basis, black broken tea began to appear and became a global bulk beverage.

5. Tea was introduced to Russia in the forty-six years of Wanli in the Ming Dynasty (16 18), when Minister China brought several boxes of tea as gifts to the Russian czar; 1638 Mongols also brought tea back to Russia. Since then, drinking tea has become popular in Russia, and tea has become one of the main commodities in Sino-Russian trade. 1833, Russia purchased tea seeds and seedlings from China, planted them in Nicht Botanical Garden, then expanded other botanical gardens, and made tea according to the laws of China. 1884, Thoreau Zuo Fu brought tea seedlings and seeds from Hankou, opened a tea garden near Batumi in Transcaucasia, and engaged in tea planting. 1893, Bobo visited a tea factory in Ningbo, bought a lot of tea seeds and seedlings, hired 10 tea workers to the Caucasus, built a small tea factory in the form of China, and produced tea according to the tea-making method in China. Since then, Russia has a tea industry.

6. Tea was introduced into Ceylon, Sri Lanka (now Sri Lanka), and there were cultural exchanges with China in the 4th and 5th centuries. Sri Lanka introduced trial planting of tea seeds from China in17th century, and then tried planting in 1780. 1824, tea varieties from China and India were introduced many times, and technicians were hired. 1869, Sri Lanka's coffee industry suffered from insect pests and decided to replace it with tea industry, so tea production developed rapidly.
