Dear Mrs Green,
I'm so glad to hear from you.What I can't wait to share with you is my participation in the study tour organized by our school last month.It is a way of exploring out of the campus rather than acquiring knowledge from textbooks.and I love it.
As scheduled,we set off early in the morning for Hancheng.Showing our admiration for the author of Records of the Grand Historian,we visited Sima Qian Ancestral Hall.Moreover,appreciating the traditional architecture as well as listening to the local stories inspired us.In the study tour,not only did we obtain valuable experience,but also cultivated the practical ability,which is of great benefit to our development.
I sincerely invite you to visit Shaanxi again.and take Hancheng as your next destination.Yours,Li Hua
