Among the three versions of "1" and "Tik Tok", the international version is rich in content, with more language choices and regional settings, which is suitable for seeking inspiration and enhancing aesthetics.

2. The regular version has the most users, but relatively few functions; Tik Tok Extreme Edition has small installation package, fast download speed, traffic saving, fast running speed, full-screen immersive ultra-clear image quality, and red envelope function to earn gold coins for cash withdrawal, which is more stable and saves traffic.

3. Which version to choose mainly depends on personal needs and preferences.
