Dear Chris,
Are you interested in coming with me to see a famous opera？It will performed at the Sichuan Opera House at 2 p. m. in May Day. I know you took great interest in Chinese culture, especially local opera. I think the perform will not only leave you with an unforgettably impression, but satisfy your interest in Chinese Opera as well. If you can come, I suggest us should visit the Sichuan Museum near the Opera House before and after the opera. You decide. The museum is hosting a exhibition on Sichuan opera. If we go, I believe you can learn many about Chinese opera in there.
Yours,
Li Hua
