之后 vs 过后 usage & differences Based on the dictionary, 之后 = after, afterwards while 过后 = afterwards, after. I wanted to find the difference in usage between those two words, so I analysed some sample sentences. I feel like 过后 is mostly used for describing "after the event" while 之后 seems to fit for anything. Is 过后 and 之后 used as I described or are there other ways to differentiate their usages?
"(noun) 之后" = "after (noun)"


Example: 

"2018 之后" = "after 2018"

"暴風之后" = "after the storm"


  "(noun) 过后" = "after (noun) had passed"


Example: 

"2018 过后" = "after 2018 had passed"

"暴風过后" = "after the storm had passed"


  "之后 (verb)" / "过后 (verb)" = "afterward (verb)" 


Example:

"之后再補償" = "compensate afterward"

"过后再補償" = "compensate afterward"


  "(verb) 之后" = "after (verb)"


Example: 

"清朝灭亡之后" =  "After Qing Dynasty ended"

"政府成立之后" = "After the the government is founded"


  we cannot use "verb + 过后".  Both "清朝灭亡过后" and  "政府成立过后" are grammatically incorrect
