How does one make sense of public opinion （PO） warfare and cognitive warfare？This paper，based on hands-on experience and observations in the U.S.，summarizes ten ways of guiding PO：a sound spokesperson system；PO guidance by mainstream media through agenda setting；senior officials delivering speeches on special occasions or signaling policy moves in interviews；release of important information by the government at certain forums；an expert team providing media with speech support and authority；intervention of retired senior officials in policymaking；the ongoing Operation Mockingbird；opinion polls as the weather vane of PO guidance；credit ratings as indicators influencing markets and investments；and suppression of foreign rivals by the government through smear campaigns. At present，the U.S. media is trying to bet against the Chinese economy. When coping with Western PO warfare，China should make good use of mainstream media like CGTN and digital media platforms，including TikTok，as well as provide PO support against the U.S. suppression of TikTok.
