How to interpret the decline in the poem of returning home?

The pronunciation of "decline" in The Return of the Native is handsome, which means: aging. When people get old, the hair in the temples turns white, for example, aging is white (when people get old, the hair in the temples turns white); Senile sideburns (old and thin white sideburns) refer to old age).

Cui was pronounced in ancient times when he was translated into mourning with raw edges made of coarse cloth.

Original poem:

"Two Hometown Couplets, Part I" Tang Dynasty: He

Young people leave home, old people return, and the local accent has not changed.

When children meet strangers, they will smile and ask where the guests are from.

Explanation:

I left my hometown when I was young and didn't come back until my twilight years. Although my local accent hasn't changed, my hair on my sideburns has become sparse. None of the children knew me when they saw me. They asked with a smile, where did this guest come from?
