The most frightening 'Quit Smoking' advertisement in history?

At the television station.

Fifth floor, Public Service Announcement Department.

Sun Han pushed open the door to the office and proclaimed, "Alright everyone, please stop what you are doing for now. I have invited someone with authority in the industry to assist us on the project for the quit smoking public service ad." Saying that, he gestured to the person beside him. "I don't suppose Teacher Zhang needs any introduction, right? You all should know him. Before we get started, I need to inform everyone that Teacher Zhang is here to help out in a private capacity and will not receive any compensation. This ad's planning will entirely be handled by Teacher Zhang. Before tomorrow's ad approval deadline, every one of us in the Ad Department will follow Teacher Zhang's instructions! Any questions?"

"No!"

"Teacher Zhang?"

"Great!"

"Teacher Zhang's ads are well-known throughout the country!"
