I'm trying to broaden up my vocabulary and try to make my It sound more professional. What steps should I take to achieve this? Please help me.

Well, looking for synonyms to words can help, try reading some more. Believe it or not, reading broadens your vocabulary. Just a few suggestions hope it's helpful :)

Explanation:

there is 2 main differences, basically which are the users and the market. the other difference is the kind of content

people who use tik tok are mainly people from east asia, kind of like the app douyin. musically, on the other hand, are used by people from america or european countries.

while tik tok videos show things like daily life videos, comedy, or just funny videos, musically are like people mimicking songs with their own actions, 'imitate' singers and video clips.

hope this !
