PRC don't have the custom of debunking every bit of western propaganda, possibly because they either naively believe that truth will defend itself or maybe more realistically because they wouldn't have time to do anything else (and westerners would take this as the lies, guilt admission or whatever anyway). USSR was the same. Sadly it does result in some even straight up nazi pieces of propaganda standing as uncontested "truths" in public spaces and it carried off to the greatly westcentric internet.
