Wangzai is a Taiwanese company.

The origins of Want Want Group can be traced back to Yilan Food Industry Co., Ltd. located in Luodong Town, Yilan County, Taiwan.

The company was founded in 1962 and was engaged in the OEM and export of canned food. However, it was run by a friend of Cai Yanming's father Cai Ashi at the time.

In 1976, the management rights were taken over by Cai Ashi. Cai Yanming, who was only 20 years old and had only graduated from a junior high school, volunteered to participate in the company's operations. The following year (1977), Cai Yanming took over the management rights as the general manager.

However, Cai Yanming, who lacked experience and ability, soon encountered huge losses. The company's launch of "Langwei Shredded Squid" caused the company to lose more than NT$100 million.

In 1979, it began to re-open the Taiwan market with its own brand "Wangzai".

Later, because he was optimistic about the huge profits of Japanese rice crackers, he approached the Japanese rice cracker manufacturer Itsuka as an OEM. Later, he obtained the technical authorization from Iwazuka and launched "Wangwang Senbei", which was a great success. The advertising effectively combined

Taiwan's folk worship habits once accounted for as much as 95% of the market in Taiwan, forcing the established food manufacturers Uni-President and Yimei to withdraw from competition.

In 1983, the trademark was named "Wangwang".
