You try to find Xu Huang.

Looking for Xu Huang seems like a very logical move. You decide to start your investigations with the obvious: a phone directory. It's just possible that Xu Huang may have a legitimate identity in Shanghai. As you search through the directory, you find several Xu Huangs in Shanghai, and also a business called "Xu Huang's Laundry and Dry Cleaning". A laundry can be a good front for other, more shady business, you think. You decide to go down and check it out.

You find Xu Huang's Laundry and Dry Cleaning in a very seedy part of town. You have a strong feeling that your hunch was right. This supposedly respectable business is in just the right place for illegal dealings. You notice a garage door where large trucks could drop off or pick up goods, and the building itself seems slightly larger than what would be needed for a laundry. Also, significantly, the business seems to closed in the middle of the day. Blinds are drawn over the windows, but you think you can see light coming through the chinks.

You consider your options at this point: you can find a window to spy at or you can knock at the door and ask for Xu Huang. After all, no one has reason to suspect you, and you can quickly think of a good reason why you want to see Xu Huang.
