Would'nt have paid that much money for it, its a bit florid.
Does however have the myth of the Chinese Dragon Gate motif.. the carp by swimming up against the currents and waterfalls, would jump over the dragon's gate and be transformed into a dragon. This symbolism occurs in many paintings which are hung in offices, etc - hard work and achievement gets you the goodies. Wonder if the Chinese will give Cameron and crew a painting to take back ;)

Also funnily enough it has the same symbolism as our celtic Salmon of Wisdom, who also has to struggle back to its home ground to breed and succeed...
