There are several extended understandings of this sentence. Some people say that the east wind was borrowed by Zhuge Liang when Chibi was on fire, which is a metaphor for God's help and spring refers to precious time. So the whole sentence means that if God can help me, I will not live up to this precious time, nor will I live up to your expectations (the implication is that I will cherish my time and strive to fulfill others' expectations).
In fact, Qing is often a nickname for men and women to express their love for each other. Therefore, according to Dongfeng's understanding, two meanings can be extended.
First, if I can get God's blessing (such as giving me wealth, power and talent, etc. ), I will cherish this beautiful spring, love you well and give you everything you want. At this time, the east wind is Zhuge Liang's intention to borrow the east wind.
Second, if I can get the attention of beautiful women, I will definitely love you and cherish the happy time with you. At this time, Dongfeng refers to metonymy, while Qing at the back is the same person and refers to the author's sweetheart.
