"Jingyu" (Gold and Earth), both characters are taboo to use in the horoscope. If you want the same name, I recommend: Chen Taiyu (fire, fire, earth). This name is good for replenishing qi and will not do much harm to the horoscope.
If you choose names based on numerology, the following are recommended: Chen Jianting (Fire, Wood, Fire) and Chen Junjun (Fire, Fire, Wood) --- basically homophonic with my brother's name.
Sancaiwuge is a name with 100 points. Qi replenishment is also relatively complete.
