Perhaps you should try some spelling variations:
ngang cho » nang cho, ngang tho, sang cho
ty ngang » ly ngan, te ngan, tu ngan
te sach » toc sach
duc van » duc va, duc manh, duc phan
hanh di » hanh vi, hanh de, hang di
cuc ban » cua ban, cac ban, cuu ban
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
cho hoc » co hoc, khoa hoc
cua cay » cua cac
ve cac » va cac, vien cac
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: te sach ty ngang cho hoc. hieu ve cac ((((duc van) OR (duc tan))) or (cuc ban)) hanh di cua cay~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ngang cho hoc. hieu ve cac ((((duc van) OR (duc tan))) OR (cuc ban)) hanh di cua cay*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ngang cho hoc. hieu ve cac ((((duc van) OR (duc tan))) or (cuc ban)) hanh di cua cay*".
