Visitors who like stamps and postcards in tourist places must come here. In fact, this museum is very small, and it takes about a minute or two to walk around without looking at anything, and there is no air conditioning inside. But the front desk staff is very good, although not Chinese, but will try to communicate with tourists. You can learn about the development of local postal services here, you can buy some stamps, you can send postcards to family and friends, one only needs 15 baht.
