Your couplets all end with wealth, so you have to distinguish between the upper and lower couplets, and you can only understand the difference from the meaning of the couplets. Because the word "Tian" in one couplet is just a passing word in the middle, while the word "Yong" in another couplet represents eternal meaning and is also the closing keyword of the couplet, so the upper and lower couplets are as follows:
Part I: Family health increases wealth.
Downstream: Ding Caixing, Wang Yonggui, Fu Gui.
Horizontal approval: Happiness is like the East China Sea.
