"Dad isn't worried about this?"
"So you think this fire protection system is a foreign import? Does it not conform to the 'Ancient Building Maintenance and Operation Procedures' you helped revise?"
"It's not that."
"Then what is it, Professor Nie?"
"Dad can't explain it at the moment."
"Professor Nie, intangible cultural heritage is the legacy of all humanity. If we're to rebuild, we need to ensure that the reconstructed Wan'an Bridge won't be destroyed every half-century. Whether it's drawing on others' strengths or using foreign methods for our own purposes, any measure that can prevent these wooden arch bridges from suffering through cycles of destruction is meaningful."
"Datou, you're right. Whether it's the traditional construction techniques of wooden arch bridges or the Dong Ethnic Group's timber building skills, as long as these traditional construction techniques are preserved, the traditional style and character of the buildings won't be lost."
