Today I went and saw 吴哥窟 (Angkor Wat), a temple outside Siem Reap, Cambodia.  It dates back to the 12th century, and numerous national governments have 赞助 (donated money to/supported) the 维护 (protection/maintenance) of the deteriorating walls.  It is indeed a 国宝 (national treasure) for Cambodia, and truly 具有代表性 (possess representative characteristics) for the country.  Entering Angkor Wat through the back gate and walking down 安静 (quiet) dirt roads made the trip all the more magical.  Although there were a handful of 旅行团 (tour groups) visible during the visit, the 人流量 (flow of people) peaked as we walked out of the front gate, where it was 人山人海 a mountain of people- see note below).
