Dear native Cantonese speakers, Below are my questions... I would love your help. Thank you! 一日要做三[?]四個鐘頭 One day, I need 3 to 4 hours. What’s the character for “to” in this case? I know it sounds like zi, but I don’t know tone nor character. Yiu3 keoi3 soeng5 tong4 is my approximation of what I heard for the word “distant learning” What’s the “yiu keoi” in this case?   Yat1 lou haang4, yat1 lou sik6. Walk while eating. “Yat lou… Yat lou…” I heard means doing something at the same time. Did you know the character for “yat lou”?   “Dai zan si sin” is my very rough approximation of what I heard for the phrase “in the future.” Did you have any guess as to what this might actually look like in chinese characters?
