Perhaps you should try some spelling variations:
than change » chain change, can change, mean change
long chain » long chemin, long grain, long han
fang than » fang yuan, fang zhen
run gain » run pain
yang yin » yang jin, yang lin, yang yun
yang yi » yang xi, yang jui
n gain » _ gain

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: fang than change ((n gain) OR (run gain)) ((((yang yin) or (yang yi))) or (yang di)) long chain ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: fang than change ((n gain) OR (run gain)) ((((yang yin) OR (yang yi))) OR (yang di)) long chain ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fang than change ((n gain) OR (run gain)) ((((yang yin) or (yang yi))) or (yang di)) long chain ;*".
