Ruan Yisan / 阮仪三

Ruan Yisan is the urban-planning and heritage-conservation figure discussed in No.209 晋商往事：走西口到乔家大院然后煤了. The episode describes him finding severe damage and demolition pressure in Pingyao Ancient City / 平遥古城 around 1980, then seeking time from provincial authorities to redo the plan for free.

The source uses Ruan’s intervention to show that heritage cities are not preserved only by cultural value. They need planning decisions, administrative pauses, expert argument, and a development path that does not destroy the old fabric before tourism value is recognized.

Key Claims

• Ruan’s role is presented as timely intervention before Pingyao’s old-city structure was irreversibly weakened.
• The episode frames planning as a condition of later Heritage Tourism Commercialization, not as an afterthought.
• His work is paired with Chen Congzhou / 陈从周’s principle for separating old-city preservation from new-city development.

Connections

• Pingyao Ancient City / 平遥古城 — primary conservation case.
• Chen Congzhou / 陈从周 — planning-principle counterpart in the episode.
• Heritage Tourism Commercialization and City Commercial Observation — broader place-development frames.
