Hi LiuYan, welcome to Roadfood. This is going to be a bit different for you to make, Cheese isn't really in the chinese diet. The potatoes should be thick skinned, they may also be hard to find, most of your potatoes are thin skinned. We use Russet potatoes, Idaho potatoes, that are named Russet Burbank an can be found in some places in China. The potato can be baked like Sundancer7 said, then hollowed out a bit, then deep fried to crisp the skin, they can be topped in many ways. This maybe the problem on your side, the sour cream may be substituted with Sour Yogurt or maybe even Silken Tofu, the bacon that we us is different but, you can use chopped crispy pork or Char Siu for the pork flavor. The Cheese is something you need to look into, Wal-Mart may have some, they may also have Cheese sauce, in jars, Nacho cheese in a jar and so on. THis may give you and idea of coming close to an American look to the dish. We used to make these a bit different in our food service, we used left over baked potatoes, chopped them up in larger chunks, deep fry and then top with Cheese melt under a broiler, then top with green onion, hot peppers, chopped bacon, sour cream. There are also other variations making them Mexican Taco topped potato skins and also topping with BBQ pork for a Texas style.................hope this helps......pnwc
P.S. the cheese needs to be a shredded melting cheese, we use Cheddar, Monterey Jack, You may have some imports coming to you from Europe, look for a soft chhese that melts when heated..........
