"Three treasures in Northeast China" refers to the northeast of China [1]? There are two versions of the three native products, the old and the new. The old three treasures: ginseng, mink, and Ursula. New three treasures: ginseng, mink and velvet antler. (Rana chensinensis oil, bear bile, honey. )
The reason why there is the "old three treasures" is that the poor people in the past filled their shoes with Ursula grass in winter to ensure that their feet were not frozen, so Ursula grass was the treasure of the poor; The rich wear cotton boots, so they don't think that Ursula belongs to the Three Treasures in Northeast China.
