多年来

• Pinyin: duō nián lái
• Hanzi breakdown: 多 = many; 年 = 禾 (grain/harvest) + 人 (person) — originally one harvest cycle = one year; 来 = 来 (to come) — up to the present

Meaning

Over many years; for many years; throughout the years. A temporal phrase indicating that something has persisted or developed across an extended period.

多年来 frames a statement within the context of accumulated time and experience. It often introduces achievements, changes, relationships, or sustained conditions: 多年来的努力 (years of effort), 多年来积累的经验 (experience accumulated over many years), 多年来坚持 (persisted for many years). Unlike 长期以来 (for a long time — more formal), 多年来 has a personal, reflective quality.

2. 两国之间多年来建立起的互信基础，使此次合作得以顺利推进。 The foundation of mutual trust built between the two countries over many years has allowed this cooperation to move forward smoothly.
