Grammar & Usage
How it works
This is a complex sentence structure. "由此可见" (yóu cǐ kě jiàn) is an idiom meaning 'from this, it can be seen' or 'this shows that', acting as a connective phrase. It introduces a conclusion drawn from the preceding context. The second part, "他的努力没有白费" (tā de nǔ lì méi yǒu bái fèi), means 'his efforts were not in vain', with "没有白费" meaning 'was not wasted/in vain'.
