Thousands of miles away, Zhang Guoqing knew nothing of what was happening at Old Zhang's family; even if he knew, it wouldn't make a difference. His parents, sure, but how can he take care of his distant nephew as well?
Since that summer, he's realized that his long-desired family bond couldn't withstand the test of time and space, so he let go of his concerns.
He sees himself as a common man, putting his wife first, but his three sons are his lifeline. Now, when his life is at a successful stage, his sons can't reciprocate with genuine sincerity.
What happens if things decline?
Whether it's their sense of entitlement to his sacrifices, or other reasons...
It's no longer important.
In the end, he's repaid what he owes, supporting his parents through their elder years; they're so far away, who will know to be grateful in the future, who even cares.
