Jigsaw¹ 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 exertion² 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 mathematicians³. To separate the nine rings which are buckled⁴ 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。
