When the transportation network was completed, local conditions of freedom were significantly improved.

漫步在阳光明媚的校园绿茵草坪上，看着那些身着校服、奔跑追逐欢笑的活泼少年，儿时无忧无虑的烂漫童年记忆仿佛重新浮现在眼前。

Walking on the sunny green lawn of the campus, looking at the lively teenagers in school uniforms, running, chasing and laughing, the carefree and brilliant childhood memories seem to resurface before my eyes.
