What is the relationship between Chinese Longquan sword and Shen GuangLong sword?
Chinese Longquan sword is synonymous with good sword. Shen Guanglong is relatively good at making Longquan swords. If your purpose is collection + practical + appreciation, Shen Guanglong is basically the first choice. It is like the difference between large-cap blue-chip stocks and small GEM stocks: Shen Guanglong is well-known and has formed a climate, and overseas markets have more recognized old shops with historical origins; although other sword shops have their own reputations, they have less cultural connotations.
