'If Not Sincere', 'Don't Disturb', also broadcast with the titles If You Are the One in Australia and Perfect Match in Malaysia) is a Chinese dating game show hosted by Meng Fei.

Loosely based on the Taken Out format, the show is produced by JSBC: Jiangsu Television and taped in Nanjing.

According to Beijing-based CSM Media Research, the audience ratings for Fei Cheng Wu Rao - which as of May 22, 2013 had screened a total of 343 episodes - were 2.77 percent of television viewers, or 36 million, twice as many as the nearest competitor for that timeslot.

[3] The pair drew inspiration from the Taken Out format, however when the rights for that show were instead won by a rival network, If You Are the One was launched instead.

If You Are the One experienced great popularity in its first broadcast because of its unique approach to dating and the conversations that are often humorous with friendly insults.

[3] Also, different from dating shows in the late 1990s, such as The Rose which mainly discussed private matters such as personality and hobbies, If You Are the One engages more with larger socioeconomic issues such as pre-marriage property notarization and gender equality.

[4] In the first half of 2010, the show broke ratings records, with some 50 million watching every episode, an audience second only to the CCTV evening news broadcast Xinwen Lianbo.

[3] In the initial format of the show, the contestants reported things such as their annual earnings, their material possessions, etc.

[5] One male contestant, a son of a businessman, was rejected by all 24 women on one episode for egregiously showing off his sports cars and bank statements instead of his life and interests.

[8] From that point forward, Fei Cheng Wu Rao was to curb mentions of financial wealth and sex, and a third host was added: a party school psychology teacher named Huang Han, who was seen to 'balance' the show to make it more grounded and less controversial as well as adding more banter between the three hosts.

Also omitted is the 'final opinions' on a departing male contestant from the women; previously this part of the show was especially prone to pointed insults and ridicule.

Moreover, the original reel of the show must undergo heavy editing before airing depending on length and number of contestants present.

Between November 19 to December 10, 2016, a series of specials titled "1vs24" was aired where the roles of the genders were reversed with 24 Males taking to the podiums to face a single female.

On December 31, 2016, the Guangdong High Court overturned the decision on appeal by ruling that "Fei Cheng Wu Rao" did not infringe on another individual's copyrights and therefore the producers changed the name of the show back to "Fei Cheng Wu Rao".

On February 3, 2018, Huang Lan returned to the show as female commentator, partnering with Jiang Zhenyu.

The single man uses two or three video clips to reveal some personal information such as occupation, interests, love history and friends' opinions.

A new procedural option, "burst light" (simplified Chinese: 爆灯), enabling a woman to signal a special interest in the man, was introduced to the programme in the episode broadcast on 20 October 2012.

It can be activated only once per round, and is heralded by a "smashing" sound cue, followed by a show of pulsating hearts, along with the number of the woman who "burst the light", on display screens around the studio.

In the 2020 version, the "Recommended Lady" (simplified Chinese: 智推女生) is then revealed, as long as at least one girl keeps her light on.

The man may insist on his "heartbeat girl", or in the 2020 version, choose his "Recommended Lady", even if they had turned their lights off.

The host and the single man then begins conversation with the women behind the screen after the selection process has taken place, followed by playing his first video.

[16] The single man uses a total of two video clips to reveal some personal information such as occupation, interests and love history.

[19] If the single man had chosen to swap out one of the finalists for one of the girls that had kept their light on in the favourites section during the round, and decides to choose the woman that was swapped into the finalists podiums after the final question round, he is able to walk to her, take her hand and leave together for a presumed future date.

[20] The girls make their entrance: In both versions, the introduction song when a contestant enters the stage is Jean-Roch's "Can You Feel It" (Big Ali Edit).

If the two female finalists are not chosen (i.e. the contestant insists on the favorite girl, or the "Recommended Lady" in the 2020 version), they leave the stage: In both versions, a matched couple leave to the tune of "You're The Right One" (“你是对的人”) by Lee Junho (이준호) featuring Qi Wei (戚薇).

An alternative outro in the 2010 version features the song Wo Zai Na Yi Jiao Luo Huan Guo Shang Feng" (我在那一角落患过伤风(小说音乐)) by Fiona Fung.

The introduction song when a contestant divides the twenty-four women as they make their entrance is Martin Jensen's "Solo Dance".
