怎么说 Visit (someone), Visit a familiar?
*We say 拜访 in this case.
比如: Today I visited my mother in law, 可以说: 我今天访我岳母, 可以吗?
(Mother in law 怎么说? 女方的岳母和男人的岳母称为不同吗?)
*It's the same. We say 岳母 for both the paternal and maternal mother-in-law.
也读过 '看望' 也有这个意思, 这个单词怎么用?
*看望 for me is only used when you visited somebody for special meaning. How to say, like you visit your grammar because you haven't seen her for a long time, and you visit a patient because he is sick. 拜访 is more casual- you visit somebody without specific purpose.
还有另一问题, 怎么说: This book is about... / The plot of this book is about,,,
有更好的样说吗?
*这本书是关于**(content)
Hope this helps :)
