I'd like to create a Chinese name (because my original name is extremely, extremely hard to pronounce for Chinese speakers) and I'd like to ask if 安大勇 is a good choice for a male name and if it brings up any undesirable associations.
Backstory: My first Chinese teacher, of whom I have very fond memories, called me 安 (after the first syllable of my name Andrew), which is a relatively common Chinese surname. However, she kept telling me that 安 is only a surname in Chinese and that I needed to add more characters - a "running joke" between us was that she would one day create a full Chinese name for me. Unfortunately, after the first semester, she died tragically and I (for unrelated reasons) stopped studying Chinese. I am now starting again and would like to choose a Chinese name. As a homage to my first teacher, I would like to use 安 as my surname.
大勇 is a Chinese translation of the meaning of my first name (Andrew comes from Greek ἀνδρεῖος, which means "brave" or "courageous"). I've found a few people with the given name 大勇 on Google (and I've also found it as the dharma name of a few Buddhist monks), so it's probably relatively common, but I'd still like to ask native speakers what they think of this choice, because I have heard that sometimes there may be a problem in the combination.
Thank you for your replies, I really appreciate your help.
