-Purely hypothetically speaking, you are at the South China Sea, arent you? At least your profile says so....
-You could by a train ticket to Shenzen, get a Visum for HKSAR this shouldnt be too hard,hypothetically speaking, since every weekend HK is deluged w/ mainlanders buying milk powder.
-Theorethically you speak Canto and can read Chinese and buy an octopus ticket, put some money on it or any daytime ticket whatever fits you.
-In any case hypothtically you should arrive at Central MTR Station.
-Being the harmless tourist you are you decide to take a ride in the world famous mid-level escalators:
https://en.wikipedia.org/wiki/Central–Mid-Levels_escalator
-Being halfway trough, you discover that it sucks and go off, say purely by chance on Hollywood Road.
-(Optional: In theory it should be nearing noon and there are a very good biryani and a nice pizza joint directly below/at the MLE.... if they are still there HK is very fast moving).
-Being the good tourist and while you are by chance on Hollywood Road, you decide to visit the Hang Mo Temple (think this was the name, one of the oldset buildings still extant in HK).
-The temple is as dissapointing as the escalator, yet on the way to it you pass several astounishing stores. Again HK is fast moving, yet the names Lee Hing, Archangel and Honeychurch may still be there.
- Those have in their windows "merchandise" that leaves you with an open mouth: Tang horses, Ghost houses, bronze age swords (I kid you not), Jade and ivory of all sorts. Shouldnt have founds its way there due to Mainland China laws, yet mhmmm there it is.
- Staff is very friendly, what is not on stock can be acquired within a few days. Maybe there is still a little earth on it, but we will fix it, n.p.

Short and purely hypothtically I am of the opnion if a (in real life non-existing) silver cross finds it way into Hollywood road, It will be more worth than melt. Perhaps even somebody there can give you an address on mainland that is a buyer ..... theoretically
