Answer: The reason why Zibo barbecue suddenly became popular is mainly due to the following reasons:

1. Regional characteristics

Zibo is located in the middle of Shandong Province. Southwest Shandong is a typical industrial city. However, Zibo is also a city with a long history and unique regional culture, and barbecue is one of the representatives of Zibo's regional culture. Zibo BBQ mainly focuses on grilled mutton skewers, which are unique and delicious. This delicacy has been in the local area for decades and is deeply loved by the locals. This regional cuisine gives Zibo Barbecue a unique competitive advantage in the market.

2. Consumption Upgrading

In recent years, with the development of our country's economy and the improvement of people's living standards, consumers' consumption levels have also gradually increased. Consumers' requirements for the catering industry are also constantly increasing. They are no longer satisfied with just filling their stomachs, but require more abundant, high-quality and distinctive food. Zibo Barbecue just meets this demand. Its unique taste and characteristics can attract more and more consumers to come and taste it.

3. Marketing methods

With the advent of the Internet era, marketing methods are also constantly being upgraded. The popularity of Zibo barbecue is also inseparable from its marketing methods. Major barbecue restaurants are using social media platforms such as WeChat and Weibo to attract more consumers by publishing food pictures and promotional information. In addition, some barbecue restaurants also use online reservations and takeout methods to facilitate consumers to purchase and taste.

In general, the reason why Zibo barbecue suddenly became popular due to its unique regional characteristics and taste, as well as the upgrade of marketing methods, is the result of the simultaneous action of many factors. This also provides inspiration for food companies in other places. If they want to gain a foothold in the market, they must not only have unique products and services, but also need to continuously upgrade their marketing methods to adapt to market changes and consumer needs
