Qian Gaochao, an inheritor of bloodstone seal carving, a national intangible cultural heritage item, recently finished a series of seals with the theme of the G20 member state leaders to celebrate the G20 summit to be held in Hangzhou in 2016. The head portrait of each leader is carved on a 4-by-5-cm seal. The works took him half a year to finish.
