The very small amounts of roasted fish come from good food products, using a particular economic fish in the mekong basin, the basalt. They are fine, nutritious and have little thorns, and they can eat with courage, both for the elderly and for children. In order to release as much fish as possible, the fish tai chi r&d team has developed a long-term study of taste packages that can make the production simple or release the taste of fish meat. At the same time, there are a variety of taste options to satisfy different consumers. Fish is a small part of the roasted fish business, with a simple sale of 1-2 people. The full package operation, therefore, is not experienced, is not technical, is not required to hire chefs and save labour. The average price is 20-30 dollars, which is affordable for everyone, and a small sum is not wasted and one person can eat a large meal. The food package is distributed in cold chains and can be processed at the shop for food, fresh food and good food。
