HI there, I will see if I can help you. 嗰處, 嗰度 mean the same thing. 嗰便 is what I considered to be a slang term but it has similar meaning as 嗰處, 嗰度 I also wouldn't use the word , 個 is the appropriate word. 你愛唔愛買花? = Do you love to buy flower? 我愛 = I love to 你中意白飯定係炒飯？ 你中意白飯定炒飯？ are these two sentences identical in meaning? I.e. 定係=定? Both sentences have similar meaning, so you can use both. I hope this helps you! Casey
