Perhaps you should try some spelling variations:
tan thanh » tran thanh, tang thanh, toan thanh
cham duc » pham duc, cham soc, pham duy
tan vanh » tan van, tan vinh, tang hanh

tu cach » tu cac

tu nang » tru nang, tu nong, tu nano
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
dai va » mai va
x hoi » xa hoi, o hoi, 5 hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cach tu nang ((x hoi) or (x ho)). hieu ve cham duc ((tan vanh) OR (tan thanh)) dai va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach tu nang ((x hoi) OR (x ho)). hieu ve cham duc ((tan vanh) OR (tan thanh)) dai va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach tu nang ((x hoi) or (x ho)). hieu ve cham duc ((tan vanh) OR (tan thanh)) dai va triet".
• Adding a wildcard symbol may retrieve word variants: tu cach tu nang ((x hoi) or (x ho)). hieu ve cham duc ((tan vanh) OR (tan thanh)) dai va triet*.
