Perhaps you should try some spelling variations:
iterative learning » interactive learning, alternative learning, creative learning
when iterative » when iterating, when integrating, when interacting
learning hold » learning how, learning help, learning has
wang liang » wang yang
ta when » a when, data when, bay when
hold yu » hold your, hold out, told you

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong di) OR (wang liang))) OR (dong sin)) yi ta when iterative learning hold yu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((dong di) or (wang liang))) or (dong sin)) yi ta when iterative learning hold yu ;*.
