Perhaps you should try some spelling variations:
hoong thang » hoong chang, hoong ang
yang guang » yan guan, yang liang
thang long » change long
yang yang » wang yang
long sam » wong sam, long span, long arm
11 gene » 1 gene, a1 gene, l1 gene
man 11 » can 11, man 21

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: ((yang guang) OR (((yang yang) OR (wang yan)))) man 11 gene hoong thang long sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang guang) or (((yang yang) OR (wang yan)))) man 11 gene hoong thang long sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang guang) or (((yang yang) OR (wang yan)))) man 11 gene hoong thang long sam ;*.
