At the meeting, the new media action of "Happy Another Year" for CCTV Spring Festival Gala in 219 was announced.

Tik Tok will carry out all-round and in-depth cooperation with CCTV Spring Festival Gala in the fields of short video announcement and social interaction, mobilize the vast number of young people, face Chinese people all over the world, replace comments with participation, guide attention with participation, and help spread the Spring Festival Gala.

Tik Tok's name has also been changed in time. If it is still called A.me, everyone may not know what it is, so it is much clearer to directly position itself as a short music video community for young people.
