Based on the research results in the field of predictions in ungauged basins (PUB) available from the literatures and our own research experiences in PUB, the methodology of PUB is generalized to include "borrowing", "replacing" and "creating" methods, according to the logic of a Chinese saying: "even a clever housewife can not cook a meal without rice". Borrowing method is defined as the method to get the data by transplanting the data from a similar region or doing interpolation among the data from the neiboughood area. Replacing method is defined as the method to mine the target data from the related information either from the same research area by simulation, assimilation and interdisciplinary studying or from other areas by upscaling and paired-catchment analysis, all with similar geographic characteristics. Creating method is defined as the method to get the data via field or indoor observation. By combining the above research methods available so far, some clues for breaking through the barriers of PUB research to find the right solutions are proposed.
