The second edition of the ‘Open the Door to Chinese Book 1’ by Polina Shinkina provides updates in some exercises on the Chinese numerals.
In order to make the Chinese numerals more comprehensible for self-learning, the examples are included into the exercises on arithmetic calculations.
The self-correction and self-control opportunities for the learners are methodically upgraded too. For this purpose the answers to the exercises on the Chinese numerals are included into this textbook.
