Reprocessing method for improving quality of semi-finished tea or finished tea

The application of the invention discloses a reprocessing method for improving the quality of semi-finished tea or finished tea. According to the method disclosed by the application of the invention, enzymolysis treatment is performed on the semi-finished tea or finished tea by using a compound enzyme preparation, and then high-temperature baking and low-temperature baking are performed so that tea leaves with improved flavor and high leaching rate are obtained; the compound enzyme preparation after being subjected to the enzymolysis treatment consists of A enzymes and B enzymes in a weight ratio of the A enzymes to the B enzymes being (3-8) to (1-5), the A enzymes comprise at least one of plant composite hydrolases, cellulase and hemicellulase, and the B enzymes comprise at least one of tannin enzyme, flavored protease, beta-glucosidase, beta-primeverosidase and laccase; and the steps of high-temperature baking and low-temperature baking comprise the step of performing short-time high-temperature treatment a
