Relaxing in Shanghai Multi-cache

! Enjoy China's First Multi-Cache !

The cache starts at position N 31°12.158, E121°23.946 and here you will find a big stone which tells you the name but also some informations about the area.

You have to solve the following riddles:

• First of all calculate the crossfoot of the size of the park in square meters (A):

N 31°12.(A*20-2), E121°23.(A*230+5)

You will need (A) later to calculate the exact position of the cache box.

• Second you have find an information board. Look below at the painted letter B and the 'graphical' information will be like a hint for you to find any of the information boards which are at several places in the park. (Any of the boards you find in the park has the same information that helps you to solve your second riddle.) Count now only the 'red' houses which has numbers on it (just from one board).

The number of the 'red' houses is (B):

• Third: Final Cache position: N 31°12.((A*B/2)*B+A+B), E121°24.(2*A+B)

The cache box is covered by a stone and is situated between two big stones.

Happy geocaching,

Small note on cache maintenance: In the future I will go twice a year to Shanghai for business reasons, but I also instructed two of my local friends in Shanghai to take care of the cache.
