I disagree with @CatinaT1 's answer #3.
From CA FTB Publication 1031, page 6:
Residents of California are taxed on ALL income, including income from sources outside California.

If the bonus was received after @shangxinwulei became a resident of CA, it is taxable by CA.
**Answers are correct to the best of my ability but do not constitute tax or legal advice.
