Perhaps you should try some spelling variations:
hanh than » hanh han, hanh nhan, hanh phan
cac loai » cac bai, cac giai, cac dai
than cua » nhan cua, thai cua, ban cua
thu sac » thu sach, thu san, thu xac
va hanh » van hanh, va thanh, va danh
cac lao » ca lao, cac giao, cac lang
hieu va » lieu va
sac ky » cac ky, sai ky
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang x hoi. ((hieu va) or (hieu qua)) ((cac lao) OR (cac loai)) va hanh than cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang x hoi. ((hieu va) OR (hieu qua)) ((cac lao) OR (cac loai)) va hanh than cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang x hoi. ((hieu va) or (hieu qua)) ((cac lao) OR (cac loai)) va hanh than cua te".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang x hoi. ((hieu va) or (hieu qua)) ((cac lao) OR (cac loai)) va hanh than cua te*.
