Article 8 of the Trademark Law stipulates that "any sign that can distinguish the goods of natural persons, legal persons or other organizations from the goods of others, including words, graphics, letters, numbers, three-dimensional signs, color combinations and sounds, and the combination of the above elements, can apply for registration as a trademark." Article 9 stipulates that "a trademark applied for registration shall be distinctive and easy to identify, and shall not conflict with the legal rights previously obtained by others." It can be seen that idioms can be applied as registered trademarks if they have corresponding distinctiveness.
