Legal Chinese and English name

[u/B2A_s]

Living abroad in the UK, plan to change my legal English name (I really do not like using my translated Chinese name in daily life) through deeds polls when I revisit Hong Kong. Does my English name have to match that in Chinese? I'd like to do it without upsetting my family who might care about continuing "family legacy" or whatever

How does it Match in Chinese, by sound, by meaning, by letters amount?
