Is the tiger called Zi Han or Zirui?

The word Zi Han is a combination, not a word, and is usually used as a girl's name.

Catalpa is a kind of tree. Ancient people often planted catalpa and mulberry trees near houses, so "mulberry" is another way of saying "hometown", and "Han" means tolerance and tolerance.

As a name, Zi Han has two advantages: First, it lies in its pronunciation, which has a lasting appeal and romantic feeling when read. Secondly, the implication is that catalpa is a kind of tree, very strong, so it means tenacious independence. Tolerance, self-restraint, rich taste, noble character and outstanding temperament.
