Betel nut, rap, and carnival:
how the Chinese brand “King of Flavor” is winning over young people
The event is organized by Hunan Kouwei Wang Group Co., Ltd., the largest producer of betel nut (areca nut) in China and the owner of the brand “口味王” (Kouwei Wang).
Key point: “520 Carnival” is their own annual marketing campaign, which the company runs under its brand. It usually takes place in the lead-up to the holiday on May 20 and includes various activities and prize giveaways.
#口味王520狂欢节
If you see the hashtag #口味王520狂欢节 on Chinese social media and crowds of people with cameras in shopping malls — know this: it’s not just a flash mob, but part of a well-thought-out marketing strategy by China’s largest betel nut producer.
Who is “King of Flavor”?
Hunan Kouwei Wang Group Co., Ltd. is a Chinese giant in the food industry, specializing in the production of betel nut (areca nut). The company is based in Hunan Province and is the market leader, controlling a significant share of sales of this specific product across China. Betel nut in China is not just a chewable snack — it’s a true cultural phenomenon with a multi-billion-dollar turnover. “King of Flavor” has bet on the mass-market segment and aggressive marketing, aimed primarily at young people.
What is “520 Carnival”?
In China, 520 is an informal Day of Love (due to its phonetic similarity to “I love you” in Chinese). The company “King of Flavor” has turned this date into its signature holiday. The 520 Carnival is an annual marketing campaign that runs from April 20 to May 31. In 2026, one of the key events took place in Chengdu in the format of a music festival featuring well-known rappers such as 盛宇 (Shengyu) and 早安 (Zao An). But beyond large-scale concerts, the campaign also includes local activities — including this event, which also took place in Shenzhen.
How does the campaign work on the ground?
1. In shopping malls or creative spaces, a photo zone is set up in a “fashion meetup point” style.
2. Participants take photos, tag them with the hashtag #口味王520狂欢节, and post them on social media (WeChat Moments, Xiaohongshu, Douyin).
3. In return, they receive a stamp at the pavilion — this is part of a quest that leads to prizes.
The campaign’s main slogan is “秒来劲” (“One second — and you’re energized”) — it plays on the invigorating effect of betel nut and creates an association with an energetic lifestyle.
Why does this work?
“King of Flavor” has built a system that creates a living infrastructure around the brand:
· Offline engagement — people enjoy participating in quests and receiving material prizes.
· UGC content — the hashtag turns participants into free advertising agents. Thousands of photos on social media create a sense of presence.
· Connection with youth culture — rap, fashion, socializing. The brand associates itself not with a nut, but with a lifestyle.
Conclusion:
“King of Flavor” is not just a betel nut producer, but an example of how a classic FMCG brand transforms into part of youth culture through well-executed offline events, prizes, and collaborations with musicians. And if in 2026 the main event took place in Chengdu, then in the next season it could appear in any other major city in China.
