Jigsaw Puzzle
拼图玩具
For Chinese who attach a great importance to the development of children's wisdom, jigsaw puzzle ("Qiqiaoban"）might be the most ideal choice. Composed of 7 pieces in a certain shape, this toy requires one's brain exertion to join those pieces into a given pattern without leaving any gaps. The puzzle ring is another well-known game. It is said to originate from the Warring States Period (476-221 BC). Appearing to be one of the most incomprehensible games in the human history, it even aroused the attention of Western mathematicians. To separate the nine rings which are buckled together or to join separated nine rings together is quite intricate indeed.
对于重视儿童的智慧发展的中国人，智力拼图（“七巧板”）可能是最为理想的选择。它由有一定形状由7块板组成，这个玩具需要一定的脑力，使这些片段连接成一个给定的不留任何空隙的图案。九连环是另一个知名的游戏。据说，起源于战国时期（公元前476-221）。似乎是人类历史上最难解的游戏之一，它甚至引起西方数学家们的注意。分离和拼九连环是很复杂的。
