The Jiuzhaigou Tourists centre is a place for science-popularization as well as for entertainment which will help increase your knowledge and give you enjoyment.
Also you can buy some little special handicrafts at the market around the road lead to Jiuzhaigou. Most of the vendors are local people. It's very cheap and traditional... if you are good at haggling... you will have funny experiences... ^_^
What to buy: Jiuzhaigou is a freen food shopping place. There on sale are various kinds of tourist products typical of Jiuzhaigou, including Thangka, Qiang embroidey, Tibetan-Qiang silver and gold handicrafts, Angelica sinensis, ginseng, Cordyceps sinensis, fritillary bulb, Cordyceps wine, yak meat, apple, persimmon, snowpear, walnut, white melon seed, Jiuzhaigou mineral water, buckthorn juice and Hongyuan powdered milk.
Btw, my favorite is barley wine... nice!!! :)))
Avoid purchasing your souvenirs at Jiuzhaigou, try Songpan instead. Almost half price.
What to buy: Tibetan style handmade crafts,souvenirs.
What to pay: An ashtray costs less than RMB20, so compare the price they ask for any other stuff you are interested in .
Along the street, you will find alot of store selling handicraft like pouches and hat. Sometime you can find interesting stuffs like beautiful craft dragger and also hand-make goat leather hat.
What to pay: Try to ask for discount as they normal will pull up the price.
Along the street or inside the JiuZhaoGou National Park, you come across very beautiful tibetian handicraft and jewellery.
What to buy: Hand make hat, carpet, little pouch, sliver wares and lots more.
What to pay: Normally the price is reasonable but you still can negotiate price with them
On completion of the Jiuzhaigou tour in the national park, there is s central spot where the majority of people would stop over for lunch & shop. Shopping means that there is a market place on the ground floor with many stores selling basically similar things.
What to buy: Items such as jewellery, bags, gifts, traditional costumes, hats...to name a few.
I didn't quite understand why there were so many stores entirely selling hair combs. The combs were made out of antlers.....
What to pay: Whatever price they ask for you can always bargain it down. (usually you may be able to pay 70-80%) If not they know you'll move onto the next store. But even paying the price they ask for is still incredably cheap considering the workmanship that goes with the goods.
