Say one and a half, one and a half mosquitoes in Cantonese, which means the same thing? Why is it different? Which one is authentic?

One and a half may be related to coins. A coin, a mosquito and a Pentagon are equal to one and a half, and 0.5+0.5 = 1, 1+0.5 is exactly one and a half. According to the encyclopedia, an article is equal to a mosquito, and an article can be divided into half. A mosquito plus half a mosquito is not half a mosquito. They are all the same. Only in this way can you say what is authentic and not authentic, and see when you feel comfortable!
