How can I know a similar or related word in Chinese?
One answer is use a Chinese dictionary 网易有道词典. Example on 培育 (on iOS app):



Since it shows 幼小生物, the word seems to be inappropriate in this context.

However, sometimes, the entry for a given word lists related words (近反义词). In this specific case it got me to jump over to 养育.





At least this seems more reasonable, although this could never ensure the most appropriate, and there is possibly a better word.
