+# Translation Style Guide
+
+## 1. Tone & Voice
+
+### Preserve original tone
+
+Maintain the author's attitude, formality, and emotional register exactly as in the source.
+
+### Synonymous substitution
+
+Use words with close or equivalent meaning where direct translation is awkward or unnatural.
+
+## 2. Vocabulary & Abbreviation
+
+### Abbreviation
+
+Apply standard English abbreviations (e.g., _info_ for information, _dept_ for department)
+to avoid overlong words,
+but only when clarity is not sacrificed.
+
+### Concise expression
+
+Prefer shorter, more common alternatives (e.g., _use_ over _utilize_, _help_ over _facilitate_)
+unless the original tone demands formality.
+
+## 3. Structural Rules
+
+### Paragraph integrity
+
+Keep the original paragraph breaks and line spacing.
+
+### Tag preservation
+
+Any inline Markdown formatting (bold, italic, code, links, lists) must be replicated exactly in translation.
+
+### Example
+
+- Before: “请保持专业语气，但避免使用过长的学术词汇。”
+- After: “Keep a prof. tone, but avoid long academic words.”
+
+### Minimal diff
+
+When translating or syncing English content against a known Chinese original,
+if the Chinese original's meaning is extremely close to the current English meaning,
+do not modify the English text.
+This is to keep git diffs friendly _(only modify parts that have truly changed)_.
+
+## 4. Exceptions
+
+- If a term has no common abbreviation, use the full word.
+- If preserving tone requires a longer phrase, prioritize tone over brevity.
+
+## 5. Original Text
