一体

• Pinyin: yī tǐ
• Hanzi breakdown: 一 = one (unified, single); 体 = 人 + 本 (person + root/fundamental — the body, substance, integrated entity)

Meaning

A unified whole; an integrated body; unity. Refers to multiple distinct elements being merged or fused into a single, inseparable entity.

Appears in many compounds and phrases: 一体化 (integration; unification), 融为一体 (merge into one unified whole), 浑然一体 (perfectly integrated without visible seams), 身心一体 (unity of body and mind). Emphasises seamless coherence — the parts cannot be separated without losing the integrity of the whole.

2. 改革方案强调经济发展与生态保护必须协调推进、形成一体，而非此消彼长的对立关系。 The reform plan stresses that economic development and environmental protection must move forward in coordination as a unified whole, not as opposing forces that cancel each other out.
