On March 23, at the Confucius Temple in Taipei, children in an architectural painting class were using pencils to draw the entire Dacheng Hall. The teacher is Li Qianlang, a researcher and painter of Taiwanese traditional architecture.

The origin of this painting class "Grandpa Li takes you to draw a house" was accidental. Chen Jiefu, the founder of Taipei's "Suyuan Book Collection" who hosted the event, came up with the idea of ​​giving it to children.
