Perhaps you should try some spelling variations:
nang dai » nang dau, nang tai, lang dai
duc manh » suc manh, duc anh, duc minh
hanh tai » thanh tai, hang tai, han tai
dai hoi » dai hoc, dai hai, dai moi
hieu va » lieu va, hieu qua

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: tu sai ky nang dai hoi. hieu va chat ((vuc van) OR (duc manh)) hanh tai cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang dai hoi. hieu va chat ((vuc van) or (duc manh)) hanh tai cua te*.
