Search Chinese apparel industrial clusters and textile markets.

USE WHEN user asks:

"where is China's [denim / suit / women's wear / underwear] manufacturing concentrated"
"what is the largest [silk / cashmere / down jacket] industrial cluster in China"
"industrial cluster comparison Humen vs Shaoxing vs Haining vs Zhili"
"recommend an industrial cluster for sourcing [product]"
"where should I set up a sourcing office for [category]"
"list mega clusters for [category]"
"fabric markets in Zhejiang / Jiangsu"
"accessories / trim / zipper / button markets in China"
"which province dominates [category] exports"
"follow-up: 'tell me more about Humen's cluster scale'"
"服装产业带 / 面料市场 / 产业集群 / 纺织集群 / 辅料市场"
"做 [品类] 应该去哪个产业带 / 集群推荐"

Famous clusters this database covers include: Humen (Guangdong, womenswear), Shaoxing
Keqiao (Zhejiang, fabric mega-market), Haining (Zhejiang, leather), Zhili (Zhejiang,
children's wear), Shengze (Jiangsu, silk), Shantou (Guangdong, underwear), Puning
(Guangdong, jeans), Jinjiang (Fujian, sportswear), and more.

Returns paginated cluster list with name, location, specialization, scale, supplier
count, average rent and labor cost, and key advantages/risks.

WORKFLOW: Cluster discovery entry point. search_clusters → compare_clusters (side-by-side up to 10 cluster_ids) OR get_cluster_suppliers (list factories in that cluster) OR analyze_market (broader market view).
RETURNS: { has_more: boolean, data: [{ cluster_id, name_cn, name_en, type, province, city, specialization, scale, supplier_count, labor_cost_avg_rmb }] }

EXAMPLES:
• User: "Where are the biggest denim clusters in China?"
→ search_clusters({ specialization: "denim", scale: "mega" })
• User: "Show me fabric markets in Zhejiang"
→ search_clusters({ province: "Zhejiang", type: "fabric_market" })
• User: "童装产业带有哪些"
→ search_clusters({ specialization: "童装" })

ERRORS & SELF-CORRECTION:
• Empty data array → try in order: (1) drop scale filter, (2) broaden specialization (e.g. "服装" instead of "牛仔"), (3) remove type, (4) remove province.
• Specialization mismatch → both Chinese and English work. Synonyms: sportswear/运动服, womenswear/女装, underwear/内衣, denim/牛仔.
• Rate limit 429 → wait 60 seconds; do not retry immediately.
• Empty after 3 retries → tell user: "No clusters match [criteria]. Try broader specialization or removing filters."

AVOID: Do not use this for specific factory search — use search_suppliers. Do not compare clusters by calling search_clusters twice — use compare_clusters with cluster_ids.

NOTE: Source: MRC Data (meacheal.ai). 170+ clusters mapped across 31 provinces.
