title: Regex find 2 words separated by one or two words
body: <p>I'm trying to build a regex that checks if there is an occurrence of this pattern: " in " followed by 1 to 3 words (which have no capitalised letter) followed by " Beijing". Any ideas?</p>
  
  <p>Examples that match the pattern:
  "in southern Beijing"
  "in the coast of Beijing"</p>
  
  <p>Examples that do NOT match the pattern:
  "in essence this is true for Beijing" (too many words in between)
  "in Northern Beijing" (word in between has first letter capitalised)</p>
