Title: 六道轮回 (Six Samsara)
Comment:
佛教的轮回：“六道轮回”，他们认为一切有生命的东西，如不寻求“解脱”，就永远在“六道” （天、人、阿修罗、畜生、饿鬼、地狱） 中生死相续，无有止息。你相信吗？

Title: 北斗七星 (Big Dipper)

Difficulty: 6.5
Best moves/pushes: 639/195
In the initial position, placed boxes and not placed boxes, draw a double "Big Dipper" (the seven stars more visible of the Ursa Major). The goals area is the Chinese number seven, 七 (by the 7 stars). The interior walls are the Chinese characters - though slightly deformed - 北斗 (above) and 星 (below), so that together with the character 七 (goals area) they form the word 北斗七星 ("Big Dipper").
