Everyone knows that Longquan Celadon, in fact, Longquan has a particularly famous thing, is Longquan Baojian. It is said that many celebrities will come to Longquan to customize a sword of their own. I took the children to the Longquan Baojian Museum to visit. It turns out that Longquan's sword has a long history. When we walked into the museum, we saw a lot of swords with the past. Children are also very interested in seeing these swords. Walking up the second floor of the museum, we saw Chinese honor sword, Pujin Tibetan sword, Jinyong Tibetan sword, etc., all of which are very famous swords. Through this museum visit, the children have gained a lot of knowledge about the sword.
