China's protection of non-traditional trademarks are mainly reflected in what aspects?

China's current Trademark Law, Article 8 provides that "any sign that can distinguish the goods of a natural person, legal person or other organization from the goods of others, including words, graphics, letters, numerals, three-dimensional signs, color combinations and sounds, as well as combinations of the above elements, can be applied for registration as a trademark." This article is not clear enough about the type and scope of protection for non-traditional trademarks and is somewhat controversial. From the perspective of legislation. From the judicial perspective. From the administrative point of view.
