Sites generally refer to the traces left by ancient humans when they were engaged in activities in a certain place, such as architectural sites and war sites. These sites have high historical value and cultural significance, but they may not have the value of tourism development.
Ruins refer to the relics or traces left by ancient humans when they were engaged in activities in a certain place, such as ancient pottery, bronze ware and stone tools. These relics also have high historical value and cultural significance, but they may not have the value of tourism development.
Heritage refers to the property inherited from ancestors, including material heritage and intangible heritage. Material heritage includes houses, land, jewels and so on, while intangible heritage includes cultural traditions, folk customs and so on. These heritages have high historical value and cultural significance, and their tourism development value is also high.
Therefore, although sites and relics are traces left by ancient humans, their tourism development values are not necessarily the same. Heritage not only has high historical value and cultural significance, but also has high tourism development value, so they are often used as tourist attractions.
