Geocache Description:

This cache is an indoor cache and the cache site is inside surroundered buildings, thus, GPS is not quite helps for this cache, listed coordinate is an entry door of a library -- Un Chau Stree public library, cache clues are hidden inside some books.

In order to check these clues, an UV light is required, firstly, you need to find the book# "796 . 51095125 SPU" -- Hiker's Guide to Hong Kong, then check page 220~225 carefully by the UV light for these invisible clues, follow these clues to locate the final cache.

In order to minimize the book missing problem(eg. lent out/occupied by other reader), I set up main book(1st) and spare book(2nd) for each field puzzel stage, but if a geocaching team visiting the cache and would like to play for a cache hunt racing, they can separate to "Group A" and "Group B", group A look for main books, an other group look for spare books, in the end, the final books of groupA & B will point to the same cache hidden location(Final hidden spot).

To make sure your UV light is workable for this cache, you can try to check the UV code for some common HK banknote(See attached photo for $10/$20) before go.

  Mon~Wed & Fri 10:00 a.m. -  7:00 p.m.

A little prize was placed for the FTF cacher, it is a same type self-made micro cache container.

Note : No UV light?? you can find a small UV light at neighbor Apliu Street(roadside vendors), price just around HK$3~4, coordinate N 22° 19.770 E 114° 09.774 (Small UV light).
