guǎng gào
advertising
In Chinese, '广告' (guǎnggào) is used to denote 'advertising'. It is used in the same way as it is in English, to refer to the means of communication between the seller and the potential buyer. It can be used in sentences like '我看到一则减肥产品的广告' which translates to 'I saw an advertisement for a weight loss product'.
