Perhaps you should try some spelling variations:
started being » started keeping, started setting, started trying
start being » start doing, start lending
ying chang » jin chang, yi chang, yin hang
zhang new » zhang wei, zhang lei, huang new
using dna » using dea, using data, using drag
yu yang » du yang, yi yang, yu fang
dna bin » dann bin, dong bin

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ying chang) OR (yu yang)) zhang new ((start being) OR (started being)) using dna bin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ying chang) or (yu yang)) zhang new ((start being) OR (started being)) using dna bin ;~".
• Adding a wildcard symbol may retrieve word variants: ((ying chang) or (yu yang)) zhang new ((start being) OR (started being)) using dna bin ;*.
