How to apply for a Tourist Visa as dependent of my husband who work in China?

It won't affects your application if you are not employed at the moment. For the first timer applicant, you need to provide the following documents:
1. your passport
2. A truly and completely filled application form affixed with one passport-size or 2x2 colored photo
3. A copy of the round-trip plane ticket
4. invitation letter with a copy of your husband's valid chinese residence visa and passport information page
5. original NBI clearance valid for travel abroad
6. original bank certificate with receipt or original passbook, updated within the month that you are applying,
7. The emergency contact information page in your passport should be filled out and photocopied.
8. marriage certificate
