Dear Sir/Madam,
It is my pleasure to invite my good friend Ms./Mr. xxx. to visit me here in China.
I have made a good plan for his/her visit in Beijing. I will bring him/her to many famous places with either beautiful scenary or historical and cultural values.I will provide accommodation for him during his/her visit in Beijing.
It would be an excellent opportunity for me to introduce our beautiful motherland to a foreign friend, should you grant her/him the Visa at your earliest convenience.
Your kind help in issuing him/her the Visa is very much appreciated.
