Perhaps you should try some spelling variations:
done using » line using, move using
using dea » using dem, using dna, using delta
hua irene » hua ren
hua chen » jui chen, yu chen, a chen
wong yue » wang yue, hong yu
lang yi » yang yi, tang yi, jiang yi
rong yu » hong yu, rong su, song yun

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

• Performing a fuzzy search may retrieve terms with similar spellings: done using dea ((hua irene) or (hua chen)) lang yi ((rong yu) OR (wong yue)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: done using dea ((hua irene) OR (hua chen)) lang yi ((rong yu) OR (wong yue)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done using dea ((hua irene) or (hua chen)) lang yi ((rong yu) OR (wong yue)) ;*".
