A Disgusting Cache Multi-Cache

Dear Geocachers,

By now, I'm sure you've seen and have experienced all sort of caches. The brilliantly designed mysteries, the beautifully crafted camo, the strenuous top-of-the-mountain cache...But have you found a really disgusting cache?

This cache is designed to gross you out! So, be prepared to be Disgusted and Scared!!!

To reach GZ, you can walk from Wo Che Estate or Exit A of Fo Tan Station, you may also reach there by bike. 

There might be some students and cyclists muggles around GZ. Remember to be stealthy and calm. We hope by the time you sign the logsheet, you would've confronted your fear in disgust and come out braver and stronger.

Enjoy the grab!

Disclaimer:
This cache is designed for people who love to be challenged and don't mind a taste of disgust. May not be suitable for children.

Note:
You will find the final coordinates at the first stop.
It will be N 22 23.XXX  E 114 11.XXX
Please place the stuff back to the original position.
