"Cha jau" () is milk tea prepared with condensed milk, instead of evaporated milk and sugar. Its taste is, as can be expected, sweeter than ordinary milk tea. In the old days, "Cha chow" was mostly drunk by older people who had "congestion" in their throats. Another saying is that drinking Hong Kong Style milk tea with added sugar will induce phlegm in the throat. As a result, a request milk of tea without evaporated milk and sugar, but adding condensed milk instead. Shortening the phrase "Milk Tea without evaporated milk and sugar" became "Cha Jau", and condensed milk is automatically added.
