Loyalty and filial piety spread thousands of miles, and poetry and calligraphy were handed down from generation to generation. What do you mean?

What you want to ask is what does "loyalty and filial piety last forever, and learning lasts forever" mean? A family can last only by virtue of loyalty and kindness, just as poems and songs can be circulated in the world for so long.

According to the experience of searching Baidu, loyalty and filial piety are passed down by the family for a long time, while learning is a timeless meaning: with a loyal and kind character, the family can last for a long time, just as poetry and songs can last for so long. Also known as loyalty and filial piety, poetry and calligraphy are timeless. It often appears in the form of couplets, breaking the civilized family style advocated by the Chinese nation, which is filial piety at home and loyalty to poetry outside.
