Shenzhen has become a hot spot for tech investment.
Tips
register
Two registers from one word. 热土 in literary / patriotic prose means 'the land one loves' (often the homeland). In business news it has shifted to mean 'hot zone, hot market' — e.g., 投资热土 (tóuzī rètǔ, investment hot spot).
memory
热 (rè, hot) + 土 (tǔ, earth / land) — warm earth. The warmth is emotional in the patriotic sense, market-heat in the financial sense.
