Gui Changjie

No verifiable public biography, career history, education, or role details could be located for Gui Changjie. Searches across general web indexes and Chinese-language sources (including the name in Chinese, 桂昌杰, combined with terms for Nanjing, investment, electronics, and deputy general/director roles) returned no matching individual.

The only concrete signals are the supplied contact details: an email at the `china-ece.com` domain and a telephone number whose `025` area code places the contact in Nanjing, Jiangsu Province. The `china-ece.com` website was not reachable during research (connection refused and request timeouts) and does not appear in search-engine indexes, so the employing organization could not be identified or characterized.

Given the absence of any corroborating coverage — no firm team page, conference bio, press mention, deal announcement, or social profile — the role descriptors on record ("Deputy Director," "Angel Investor," "Seed round") should be treated as unverified database entries rather than confirmed facts.

• No stated investment thesis, sector focus, check size, or stage criteria could be found in any public source.
• The only stage indicator on record is "Seed round," and the only role indicator is "Angel Investor" — neither could be independently confirmed.
