Carry forward China and strive for self-improvement: it contains four connotations: first, "patriotism first, rejuvenating China"; Secondly, it is "rigorous, realistic and pragmatic"; Once again, "love the school as home, love the post and be dedicated"; Finally, it is "pioneering and innovative, hard work."

It means waiting. Together, the four words mean waiting for the fruits to ripen, that is, cultivating talents, and at the same time making talents more pragmatic and clean, so as to revitalize China.

Self-improvement: the original meaning is that the sun, moon and stars in the sky move around the clock forever. For Jiaotong University, it means the spirit of never stopping, overcoming difficulties and working hard.
