Yar, just enjoy your trip and take plenty of photos. But let me tell you that quality of products made for China by Chinese is much much better than the products made by China for Pakistan. But accordingly, prices are higher in China. And do check out taobao.com for a price comparison. Use Google Chrome to translate Chinese to English and you should be able to decide what to buy. Download a translation software into your mobile too as very very few people speak or understand English, especially in smaller cities or towns. Youdao is a nice translation software. Wish I could accompany you but best of luck and enjoy your visit!
