My dear Jack,I feel most embarrassed in referring to a rather difficult subject.
I wonder if it may have slipped your memory that nearly three months ago you asked me for a loan of RMB500.
You said you woud make repayment on the next pay day.
Perhaps you may make the repayment within 2 weeks.
I am sure you will agree and not be offended at my request.
Here is a good news for you.
The Russian National Ballet Troupe,which is now on a visit in Beijing
will give a performance in the National Grand Theater tomorrow evening.
I am sure you will be happy to watch it.
Here I leave you an admission card.
The performance will begin at seven o'clock sharp.
I will expect you at the theater entrance.
Please let me know if you are prevented from coming.
Yours sincerely, Li Ming.
