On the morning of November 3, the Weibo hot-search list carried the topic “Xiao Zhan Xiao Cheng Liang Fang CSM ratings” (肖战小城良方csm的收视率) at No. 19 — the Weibo topic around Xiao Zhan's new drama 《小城良方》 (Xiao Cheng Liang Fang) [1]. The phrase promises a number. The number it names is client-delivered: CSM Media Research publishes no drama-level figures on its public site, and its per-drama data moves through products delivered to broadcasters, advertising agencies and media researchers [2][3]. What circulates publicly instead are two claims that cannot both describe the same measurement. An opinion columnist writing on Tencent News on October 29, five days before the topic trended, cites CVB, the ratings data system operated under the National Radio and Television Administration's big-data audience evaluation system, for a figure of around 1.4% since the show premiered [5]. Hype claims about a “peak above 3%” travel without any named source, and the columnist rejects them [5]. As of November 3, no public table from either system naming the drama had surfaced, so the argument runs on figures that, in public, exist only as claims.
The CSM number stays behind a client wall by design
CSM's own materials explain where the number the topic asks about lives. The company describes itself as a joint venture mainly co-funded by CTR Market Research and Kantar Media, established December 4, 1997, running a measurement panel of close to 50,000 households that it says represents the viewing of close to 1.28 billion people in mainland China [2]. Those panel figures are the company's own descriptions.
The company reports “hundreds of clients from broadcasters, advertising agencies and media researchers” and describes measuring live viewing, time-shift viewing and cross-media behavior [2]. The drama product follows the same logic. CSM's Research Insight page describes TV Drama Express, a monthly newsletter “sent freely to our clients,” carrying TVPRIS data that answers questions like “which TV drama will be the rating champion during golden time at night in 80 Chinese cities” [3]. The public-facing description of this data speaks to clients, not to the public.
So when people search for the “CSM rating” of 《小城良方》 (Xiao Cheng Liang Fang), they are searching for a number whose documented distribution channel is a client newsletter. With no public document behind the number, secondhand claims end up doing the work of evidence in the argument around the show.
Two measurement systems, and two claims that never touch
Only one of the two claims now circulating comes from a named measurement system, and only that system has a public surface. CVB's site maintains a golden-period drama table with columns for drama, episode count, rating, share and channel, and a ratings-bulletin section [4].
Ma Qingyun, the October 29 columnist, writes that within the film and TV industry “only CVB is looked at” (影视业内，只看CVB), and he cites it for this show: around 1.4% since premiere [5]. The same column places the drama in CCTV-8's prime-time lineup this year and describes it as a medical-themed modern urban comedy [5]. Against the 1.4% he lists three dramas from that same period with average figures of 2.226% for Wo de Shan yu Hai (我的山与海), 1.910% for Chunzhen Niandai de Aiqing (纯真年代的爱情) and 1.864% for Dongqu Chunlai (冬去春来) [5]. By the numbers he cites, the show's roughly 1.4% sits below all three. That reading is arithmetic on his cited figures: it is his comparison of CVB-cited data, and this article adds no verdict on the drama or its lead actor.
The “peak above 3%” claims travel without that scaffolding. No table, announcement or original post behind them has surfaced as of November 3; publicly, they exist as a claim the columnist rejects [5]. The two claims are not answering the same question, either. CSM's own glossary defines Rtg% as “the rating in thousands of a period, divided by the universe of the target worked on,” and Shr% as the share of total television audience a channel or program captures [3]. The company counts live and time-shift viewing as separate measurements [2]. Peak versus average, one system versus the other, single day versus since premiere: each choice moves the number.
Every figure attached to the show so far is missing at least one of those elements. The columnist's CVB numbers carry a named system and a level, but the tables behind them have not surfaced publicly. The 3% claim carries none of the three.
Where a checkable answer can come from
Two things would settle the question. A CVB golden-period row naming the drama would put both circulating claims against one published line: the 1.4% citation and the 3% hype would each stand or fall against the same table [4]. A CSM figure is different, because it reaches the public only through one of the company's clients or a report of one, so the check is the attribution: who released the figure, for which panel, on which day [2][3]. Either way, the figure worth carrying forward is one attached to a table or a named releaser; everything else is the same claim in new packaging.
Until a published CVB row or an attributed CSM figure appears, the show's “CSM rating” stands as one circulating claim with a named source, one with none, and no public table from either system behind either as of November 3 [1][5]. The hot search proves people care about the number. It does not supply one.
