It is appropriate to use that character with "桢" in the name. The matching character must be of the water element.

○Gao·Wanzhen

There is a poem by Yuan Zhen of Tang Dynasty: "Officials and Cao have three words to say, and national weapons are in search of Zhen."

The allusion of "Three Languages" is incorporated into the poem

Ten thousand words and five elements belong to water

○High·Guozhen

Meaning As "the pillar and pillar of the country". The word "国" can also be used as "国", but the three words have the same sound, and they sound peaceful

○Gao·Jizhen

Taken from "The Book of Songs·King Wen": " The kingdom suppresses life, maintains the Zhen of the Zhou Dynasty, aids many scholars, and brings peace to King Wen."

Gao and Zhen both sound the same, but it doesn't sound smooth when put together, so it is recommended to put Zhen at the end.
