Ng won the Amused Moose Laugh-Off 2016 and was runner-up in the
Laughing Horse New Act of the Year 2015. He was also a finalist in the
Leicester Mercury Comedian of the Year (2016) and Leicester Square New Comedian of the Year (2015). He was nominated for the "Best Newcomer Award" for his stand-up comedy show at the
Edinburgh Fringe Festival in 2019. The accent Ng uses for the Uncle Roger character has received criticism for perpetuating negative stereotypes about Asians. Chef
J. Kenji López-Alt (who is of Japanese descent) said, "I don't like that [Ng's]
schtick seems to give a free pass to people to imitate stereotypical Asian speech patterns and pronunciation, especially as it's almost always non-Asians doing the imitating. It's ugly, it's
yellowface, it's not funny, and it promotes anti-Asian racism at a time when Asians are already being heavily discriminated against." In response, Ng has said that simply speaking in an exaggerated accent is not an indication of discriminatory behavior especially being a
Chinese-Malaysian national himself, this highlights the difference in the perception of
Asian stereotypes between Asians living in Asia and
Asian Americans. His critique video of Patel's egg-fried rice has been described as making the viewers "fall for every cultural 'trap' his character sets", overlooking the differences of rice cooking methods in
Indian cuisine, and turning East and Southeast Asians into "rice-cooking supremacists" with his "faux encouragement". On January 12, 2021, Ng apologized on the Chinese social media platform
Weibo and deleted a video featuring fellow YouTuber
Mike Chen, who had been critical of the
Chinese Communist Party and had also been associated with the
ultra-conservative movement
Falun Gong. He stated, "This video has made a bad social impact... I wasn't aware of his political thoughts and his past incorrect remarks about China. I hope you can give Uncle Roger, who has just entered China, a chance to improve!" His response attracted criticism on
Twitter. In his first subsequent video as Uncle Roger, he said he would "keep making funny videos [...] no politics, no drama". On July 30, 2023, Ng stated in an Uncle Roger video, "Not all Southeast Asia has good food. You don't want food from
Laos and
Cambodia." He also jokingly described
Laotian food as an inferior version of
Thai food, causing criticism and backlash from both Laotian and Cambodian communities. In a response video to Laotian chef Ae Southammavong challenging him to try Laotian food she had cooked, Ng accepted the challenge and explained his comments by saying, "All the Laos food I had so far... not my favourite. Asian people criticizing other Asian people is just a way of life."
Cambodia's Ministry of Tourism issued a statement condemning Ng's remarks as damaging to the image of
its cuisine and demanding an apology. The Embassy of Malaysia in
Phnom Penh distanced Malaysia from Ng's remarks, saying that "[t]hey do not in any way reflect our view". Ng has stated that he does not want any of his viewers to spread hate towards anyone. On May 22, 2023, it was reported that Ng's
Bilibili and
Weibo accounts had been closed down in response to perceived criticism of China's government in his stand-up comedy special for the phrase "this Nephew using
Huawei phone, they all listening." == Business ventures ==
