Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc dan » thuc hanh, hoc dan, thuc vat
thuc day » thuc vat
khach ty » sach ty
vu khach » vu khanh, vu khac, vay khach
thuc va » thuc vat
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
danh di » danh du, xanh di, danh dien
ve nam » he nam, va nam, le nam
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu khach ty nang xa hoi. hieu ve nam ((((thuc va) OR (thuc day))) or (thuc dan)) danh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach ty nang xa hoi. hieu ve nam ((((thuc va) OR (thuc day))) OR (thuc dan)) danh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach ty nang xa hoi. hieu ve nam ((((thuc va) OR (thuc day))) or (thuc dan)) danh di cua triet*".
