Perhaps you should try some spelling variations:
thuan wei » hua wei, han wei, tun wei
shang hai » shang kai, dang hai, chang ha
nam binh » cao binh, tam ninh
nam dinh » tam ninh
wei shen » kwei sheng, enwei shen, wei shang
yang jin » yang jie, yang jun, ying jin
yang xi » yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((nam binh) OR (nam dinh)) thuan wei shen ((((yang jin) or (yang xi))) or (yang di)) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nam binh) OR (nam dinh)) thuan wei shen ((((yang jin) OR (yang xi))) OR (yang di)) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nam binh) OR (nam dinh)) thuan wei shen ((((yang jin) or (yang xi))) or (yang di)) shang hai ;*".
