This is an old saying that was used in the olden days.
This is a phrase from the olden days. It is a metaphor for a person whose fortune is as great as the East China Sea and whose life span is as long as that of Zhongnan Mountain.
There are two sources for the phrase "Blessed as the East Sea, Longevity as Long as Nanshan Mountain":
1. Ming Dynasty's Ke Danqiu's "Jing Hairpin Records - Celebrating the Birthday": "We all wish for the blessing of Blessedness as the East Sea, and Longevity as Long as Nanshan Mountain."
2. Ming Hong (2), "Qing Ping Shan Tang Jiu Ben Hua Lan Sedan Chair Lotus Woman Becomes a Buddha": "Longevity is as good as Nanshan Mountain, and good fortune is as good as the East China Sea. From now on, children and grandchildren prosper, each going to the Dan Di."
Expanded:
1. 清-石玉昆《三侠五义》第四十二一："Lift the eight pots of pine scenery out of the crate and take a look, but it's the eight big characters of 'Fortune is like the East Sea, longevity is more than the South Mountain' tied up with pine needles, but it's also done in a novel way."
2. Qing Wu Corns "confused world" Volume VI: "Liang tailor hastily cut according to the size of the wife's clothes, and cut the old lady's birthday suit, a mouth also said a lot of "Fu Ru East Sea, life than Nanshan" words."
3. Ming Kanghai's "A flower - Shouwang ripple pattern" suite: "Shoubi Nanshan is still grassy, Fu as the East China Sea Ren Chaoyang. "
