The next morning, Mr. Ma came to his office and brewed a steaming cup of tea.
The tea aroma wafted up, and he gently blew on the floating tea leaves. Just as he was about to take his first sip, "knock knock knock"—a crisp knocking sound interrupted his action.
"Come in."
Mr. Ma put down his teacup and looked up towards the door.
Li from the secretary department pushed the door open and entered, holding a manila envelope in his hand.
"Good morning, Mr. Ma!"
Li greeted with a smile, "This is the letter of gratitude sent from Chuan City yesterday."
"Because you went out for a meeting after work yesterday, I didn't get a chance to pass it to you."
"I hurriedly brought it to you first thing this morning."
"A letter of gratitude?"
Mr. Ma took the envelope with a slight look of doubt, his fingers gently stroking the paper surface.
"Do we have any recent business interaction with Chuan City? Why suddenly..."
As he mumbled to himself, he was about to open the envelope.
