"EPCO" - 应确认是否需要大写或小写。若为简称可不改，若需常规形式请用“Epco”。 其他部分均无错误。 --- 【第 2 段建议】: 1. "high-Quality" should be "High-Quality" (capitalization). 2. "Huaxin·2026 China High-Quality Aggregate Production and Application Summit Forum" should consistently use either "·" or "." (punctuation consistency). 3. "Mr. Fang emphasized that while the aggregates industry is undergoing significant green transformation and intelligent upgrading, its core values—supporting livelihoods, pursuing high-quality products, and adhering to technological innovation—remain unchanged." (hyphen uses should be em dashes). 4. "four key propositions" is plural, so there is no issue. 5. "the application of AI and other advanced technologies" should be refined to "the application of AI and other advanced technologies," not connecting to the previous sentence unnecessarily (punctuation adjustment). 6. "more than 30 overseas offices" should use "over 30 overseas offices" for parallel structure with the earlier phrase (consistency in language).
