According to the regulations of China Banking Regulatory Commission, a loan cannot be extended more than twice, that is, a single loan can only be extended once at most. Moreover, it also stipulates the extension time, which shall not exceed half of the original loan term. For example, if the loan term is 1 year, then the loan extension application can only be extended for 6 months at most. Therefore, the number and time of loan extension are limited, and the loan extension application submitted by users may not be approved by the lending institution.
