Perhaps you should try some spelling variations:
juan meng » juan rene, jui meng, yuan ming
wong shiu » wong siu, cong shu, song shin
using ya » using a, using _, using ai
using 4d » using _, using a, using ai
hua rene » juan rene
thi wong » thi hong, thi mong, t.j wong
hua ren » hua chen
yan thi » yan zhi, tran thi, dang thi

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: done ((using ya) OR (using 4d)) ((((hua rene) OR (hua ren))) OR (juan meng)) yan thi wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done ((using ya) OR (using 4d)) ((((hua rene) or (hua ren))) or (juan meng)) yan thi wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: done ((using ya) OR (using 4d)) ((((hua rene) or (hua ren))) or (juan meng)) yan thi wong shiu ;*.
