Dear Rick, 

How is everything going? I had a five-day trip to London last week. I would like to express my gratitude for your hospitality and kindness when I was in London. 

Knowing that you take a great fancy to Chinese culture, especially the Dragon Boat Festival, I would love to introduce it to you. The Dragon Boat Festival, one of the most traditional festivals in China, falls on the May 5th in the lunar calendar. People celebrate this festival in memory of Qu Yuan, who was a Chinese poet. Besides, people in China will also hold a variety of activities to honor him, such as dragon boat racing、eating zongzi and so on. 

Welcome to China.You will have an unforgettable experience if you come to China before this festival. 

Best wishes. 

Yours sincerely, 

Li Hua
