there are five chinese characters and they are "che nan shiang fo chou"

"che nan" is the sanskrit transliteration for

1 Lignum
2 Aquilaria agallocha Roxb

(both from translation software or website
only for your reference )

shiang could be translated into incense or parfum. the mandarine shiang is pronounced "Hong" in cantonese. so the cantonese pronunciation Hongkong is shiang gang in mandarine which literally means the "incense port"

fo means buddha and chou bead
so fo chou is prayer beads.

Frederick II did a good interpreter job on this strand
