There are three necessary factors that must be paid attention to when choosing a name:

First, it must meet the requirements of numerology;

Second, it must meet the rhythmic standards. The tone of voice should be varied so that it sounds loud and pleasant;

Third, it must be given a certain meaning and express something ideological.

So from this most basic requirement, I think Zhang Siying is better.

1. Eight-character numerology requirements (I skipped it because I didn’t know).

2. Si is one tone in Pinyin, and Ying is the third tone. There are changes and it sounds nice.

3. Siying can be understood as novel thinking, active thinking, innovative spirit, unique ideas, etc., which is highly recommended.

4. Thoughts: The five elements are gold, and the meaning of the name is to be talented and sensible, diligent and thrifty, to bring prosperity to the family, to gain both fame and wealth, and to work hard in old age.

Ying: Five elements of wood, the meaning of the name is wisdom and courage, clear sense of justice and benefit, ordinary middle age, good luck in old age, and prosperity of two sons.

Relatively speaking, the meanings of names are pretty good.
