Because the word catalpa is unlucky.
In ancient times, catalpa trees were heavily yin-qi, and were mostly used as longevity materials, that is, coffins. The catalpa tree grew up hard, but it was used as a coffin after it became a success. In the eyes of the ancients, it was particularly unlucky to use the word catalpa for names.
The emperor's coffin is called Zigong. Anyone who knows the history of China should know that in ancient times, the items used by the emperor had their own proprietary names to distinguish them from ordinary people, thus demonstrating their authority and status.

1. avoid collocation with uncommon words.
Zi itself is not an uncommon word, and it is often used to name children. When naming children, we should be careful not to match other uncommon words, so as not to affect the overall quality of names.
2. Avoid matching words with unknown meanings.
The word Zi itself has a good meaning, but it doesn't mean that it can be matched with words with bad meaning or ambiguous meaning. No matter how many words are in the name, make sure that the meaning of each word is good.
For example, some words with bad homophonic meanings, words with bad meanings and ambiguous words are not suitable for collocation, which will affect children's fortune to some extent.
