Where is the best place to travel on the China-North Korea border?

1. Korean people have very strict etiquette. The younger generation must use honorifics when speaking to the elders; when traveling with the elders, the younger ones must walk behind the elders; when meeting the elders they know on the road, they must say hello and give way. Koreans respect their elders very much, and younger generations are not allowed to drink or smoke in front of their elders; when smoking, young people are not allowed to borrow fire from the elders, let alone pick up the fire, otherwise it is considered a disrespectful behavior.

2. Koreans like to eat dog meat, but they do not eat it at weddings, funerals and festivals. It is taboo to call people "Xian".

3. There will be North Korean soldiers stationed in the border areas. If you go to the southern slope of Changbai Mountain, you should be careful not to cross the border.
