In terms of the appearance of something, there a lot of HSK5 words that are very similar. Here are four and the definitions I've found thus far.
表面 - 1. surface (tangible, 方面 is intangible), 2. outside, appearance (表现 is more behavioural, subjective, the way something comes across)
形式 - n. outer appearance, form, shape
样式 - n. type, style
方式 - n. way, manner, style, pattern
Is there a clear way to distinguish between 形式，样式 and 方式? They all seem very close to each other and am not sure how to separate their usages.
