to integrate into sth
🛤️🔗 接轨 = 接 connect + 轨 rail-track = join the rails together
接 means to join or connect; 轨 is a rail or track (same 轨 as in 轨道, orbit/track). Literally connecting two railtracks so trains pass through — used figuratively for integrating one system into another.
接 — hand 扌 + concubine 妾 (phonetic)
接 is a semantic-phonetic compound. The hand radical 扌 carries the meaning of receiving or joining with the hand, while 妾 supplies the sound. From 'taking with the hand' it broadened to 'receive, meet, connect, join together'.
