I blacked out Sima Nan, not interested but always recommended. Then there is also doubt, I wrote a high click rate, but the amount of impressions is very small, can have 20,000 are the best, most of them are not more than 10,000, just 1000 to 3000 impressions, good writing does not push, casual writing does not push, I am not interested in but has been pushed, too confusing.
