Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
rene yuan » meng yuan
yuan kang » yuan wang, yuan chang, chan kang
kang hong » kong hong, wang hong, kang young
using ya » using a, using _, using ai
using 4d » using _, using a, using ai
hong yu » wong yue

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "done ((using ya) OR (using 4d)) juan rene yuan kang hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: done ((using ya) OR (using 4d)) juan rene yuan kang hong yu ;*.
