Dear Lisa,
How are you doing? Knowing that you are a lover of Chinese poetry, I am writing to tell you something about the Forum on Chinese Poetic Culture held last week.(高分句型一)(写信目的)
The event took place on March 6th in the cultural hall of our school.(时间和地点) Some experts were present and gave lectures. Our school teachers and students, together with some lovers of Chinese poems exchanged ideas on the subject.(活动的内容) Everyone present could feel the beauty of Chinese poems, benefiting a lot from the activity. Had you attended it, you would certainly have a better understanding of traditional Chinese culture.(高分句型二)(活动的效果)
Best wishes.
Yours,
Li Hua
