I am in Suzhou, and my company asked me to go to Malaysia for two months on business.

1) First, you apply for a one-month tourist visa in the mainland. After the expiration, you apply for extension in Malaysia, but you have to bear certain risks, that is, your application for extension may not be approved for 30 days, and you may only be given 14 days.

2) You have entered the mainland many times. After staying in Malaysia for 30 days, you can choose to leave Thailand and then stay for a few days before entering Malaysia. Similarly, there are certain risks. Entering Malaysia from Thailand may only stay for 14 days or even 7 days.

3) Finally, if you want to work in Malaysia, please ask a Malaysian company to apply for a short-term work visa for you.
