Jieyang / 揭阳

Overview

Jieyang / 揭阳 is represented by two source-bounded layers: an ancient southeastern location where 余善 halts his promised supporting force during the Western Han campaign against 南越, and one of the three modern cities commonly used to define Chaoshan / 潮汕.

Current Profile

Hanji 355 uses Jieyang as the stopping point that makes Yu Shan’s promised support measurable. He reaches the location with a reported eight thousand troops, cites dangerous seas, and does not proceed to Panyu before the city falls. The page does not assume that the ancient administrative unit and modern prefecture-level city had identical boundaries.

The modern layer comes from the Chaoshan business-history episode. It names Jieyang as part of the post-1991 structure created when the old Shantou area was divided into Shantou / 汕头, Chaozhou / 潮州, and Jieyang. That source treats administrative division as part of the region’s development problem: duplicated infrastructure, local competition, and weaker coordination can make Merchant To Industrial City Upgrade harder when a region already lacks Shenzhen / 深圳-level policy scale and external proximity.

Key Characteristics

• Ancient southeastern place-name in the Nanyue-Dongyue campaign field.
• Location where Yu Shan’s promised supporting force stops instead of reaching Panyu.
• Modern prefecture-level city included in the common three-city definition of Chaoshan.
• Post-1991 administrative unit created from the division of the old Shantou region in the business-history source.
• Example of why a stable place-name does not imply stable boundaries or one administrative identity across time.

Evidence

• Ancient campaign location: Hanji 355 says Yu Shan reaches Jieyang, stops on the ground of rough seas, and never joins the Nanyue attack.
• Modern regional identity: Chaoshan past names Jieyang with Shantou and Chaozhou as the core modern Chaoshan city set.
• Administrative-fragmentation role: Chaoshan past treats the 1991 split as weakening coordination and encouraging duplicated development.

Qualifications

The sources do not establish continuous boundaries, jurisdiction, or institutional identity between ancient Jieyang and the modern city. Hanji 355 supplies only a campaign waypoint, while the modern episode supplies only a regional-economic role after 1991. Exact ancient geography and the full administrative history require specialist sources.

What Changed

• Added the Western Han campaign layer in which Yu Shan halts at Jieyang instead of joining the Nanyue attack.
• Migrated the page to synthesis-v1 while separating name continuity from claims of identical administration.

Relationships

• 余善 - ruler whose force stops at Jieyang during the Nanyue campaign.
• 南越 - campaign destination that Yu Shan’s force never reaches.

• Chaozhou / 潮州 - neighboring modern city in the post-1991 regional structure.

• China Special Economic Zone Asymmetry - reform-era comparison explaining why the wider region did not follow Shenzhen’s path.
