I bought a diamond ring from Liu Fu.
The same style, the diamond is slightly smaller by two points, the counter price in Shijiazhuang.
After 75% discount, it's still more expensive than Hongkong 1500 yuan.
I bought it in Hong Kong, 4800 Hong Kong dollars, which is 4300 RMB.
Shijiazhuang sells 5800 (the price after 25% discount)
