Honestly, there are not many true specialty products. The so-called specialties are just Bu Laolin candy, which is sold in supermarkets. The original poster can buy some Northeast specialty hazelnuts; many roadside stores have signs saying Northeastern specialty hazelnuts! As for the three treasures of Northeast China, forget it. Those things are expensive, and besides, they are not products of Liaoning.
Wish you a pleasant journey!
