we used long beans egg susage and ba kua... we didnt know how to cook the long bean.. so we just anyhow cook.. we added soya sauce first.. but no taste.. then we added salt.. still no taste.. then we added oyster sauce.. lol.. then it became very dry so we added water.. lol.. we are so lousy.. but overall.. the whole thing turns out to be okay.. only that it was quite bland.. so.. the only solution was to add soya sauce..haha..
