I don't like 马力平 since she is the only author to create that book。However, I like 暨南大学的《汉语》,《中文 because there are a group of people who co author the book. 马力平must make a lot of money from Chinese school. Those books are bad and expensive. 55 for one book. while 暨南大学的《汉语》,《中文are free. you could download.
