These 2 places are quite nice to visit, if you want to buy some local sweets/souvenirs. The Chinese seal is worth shopping for here but be warned, some of the people ask tourists to pay up first then wait for the name to be carved. This is wrong! I met 1 Korean guy who had paid for the seal already but waited for more than 1/2 an hour and the man gave him lots of excuses!
Fret not, there are some others who are honest and bargaining is allowed. They will accept payment after they carved your name on the seal.
