"rollover term deposit is a fine way of saving if you are prepared to put money away for an extended period of time. An automatic rollover term deposit allows you to leave instructions with the bank to renew your deposit after a certain period of time has elapsed. You can choose at the point of rollover to withdraw the interest and leave your original capital to accrue interest again. Alternatively, you can leave the whole lot in there to accrue yet more interest, or withdraw it all on maturity. " extracted from source below. Chinese equivalent is also provided in the reference.
