Sixty-nine-year-old carpenter and grandfather Li Shishui from Longyan City in east China's Fujian Province, made his grandson a wood tank to celebrate China's National Day. The intricate toy garnered wide attention among netizens again after Li made a wood "mantis cart" which delighted millions of viewers not long ago. Li was a carpenter for more than 50 years, and now spends his retirement years making wood toys for his grandchildren.
