In the antique shop, "running the front line" means going deep into the countryside, going from door to door to explore antiques and treasures, and visit rare treasures.
Craftsmen are repairing cultural relics in the Forbidden City, and runners are searching for treasures in the streets and countryside. The mottled time, the hardships of transmission, the chance and necessity of acquisition are all condensed into an old thing, glowing with an incredibly dazzling light.
Appreciating antiques is like having a conversation with the ancients. Sometimes the signal is clear, and the ancients talk as if they are right in front of you; sometimes you are caught in the fog, and you seem to see them, but across the rushing river, you are on this bank and they are on the other bank. The river is time and cannot flow back.
