1. The finest sight: broken tiles, dung

   Asked by fellow Korean travelers what the most spectacular sight in China was, Pak passed over the palaces and the Great Wall and named the rubbish: broken roof tiles and heaps of manure. Qing villagers set shattered tiles into walls in decorative patterns instead of discarding them, and gathered dung so carefully that it was piled into neat squares and sold as fertilizer. He took this systematic reuse of waste, not imperial monuments, as the real evidence of a civilization's strength.

2. Adopt useful techniques whatever their source

   Joseon elites despised the Manchu Qing as barbarians and saw Korea as the last true heir of Ming civilization. Pak argued that this pride kept Korea poor, because refusing Qing bricks, kilns, carts and farming methods over their rulers' ethnicity sacrificed the people's welfare to a symbolic grudge. A technique should be judged by whether it improves daily life, not by the political legitimacy of whoever currently uses it.

3. Carts make roads, not the reverse

   Koreans said they could not use carts because their country was mountainous and lacked roads. Pak reversed the causality: roads appear once carts are in use, because traffic creates the demand for paths and then wears them in. Without carts, goods could not move between regions, so surpluses rotted in one province while another went hungry. Waiting for ideal conditions before adopting a tool guarantees those conditions never arrive.

4. Fear enters through the senses

   Pak crossed a river nine times in one night. By day the rapids terrified travelers through their eyes. In the dark he could not see the water, so its roar filled him with dread through his ears. Once he stopped attending to either sense and steadied his mind, he crossed calmly. Danger is not measured directly. It is felt through whichever sense dominates, so the sensation should be treated as a signal to examine rather than a fact.

5. Borrow useful methods regardless of their source

   Joseon elites despised the Manchu Qing as barbarians who had usurped the Ming, and they refused to learn from them. Pak argued that techniques which improve people's material lives (iyong husaeng, 'benefit use, enrich life') should be adopted whatever the ethnic or moral standing of the people who developed them. Rejecting working methods out of loyalty to a vanished dynasty only keeps one's own people poor.

6. Carts and roads as economic circulation

   Pak saw that Joseon's poverty came less from scarcity than from immobility. Without standardized carts and roads built for them, goods could not move between regions. That left one province with a glut while another suffered shortages, and prices diverged wildly. Infrastructure for moving things turns local surplus into shared wealth, so neglecting transport keeps a whole country poor even when it produces enough.
