Is it normal that my adviser remove my information, pictures, everything from the lab homepage after I suspend my school?
Consider your relationship with the professor at the time that you left. There are at least two cases I can think of where a professor may remove your information from the lab page.


You didn't finish, and you are no longer part of the lab (not quite alumni). It's not clear if you will finish. A lot of unfinished students can make a bad reputation for the prof.
The professor does not want you to represent the lab.


As you probably know, Asian culture is a lot about 'saving face'. The professor may feel disrespected by you taking a job before finishing the thesis. Or possibly even taking the 'wrong' job.

One place that the professor is very, very unlikely to remove your name is the lab publications list. Work on publication, and use that as your work reference rather than the lab webpage.

If possible, try to discuss your research with the professor.
