Ms.claudine, I heard a bad piece of news that the China embassy in Doha, Qatar doesn't accept individual tourist visa application from Qatar passport holders, but I don't know whether Lebaneses can apply for individual tourist visa, you'd better first enquire the embassy.

As I know, for a tourist applicant, in principle he shall evidence his financial capability of covering the travelling expenses in China, and when necessary, provide the air, train or ship tickets to the heading country/region after leaving China.

the applicants' passport, one completed visa application form of PRC, and the work permit in Qatar (non-Qatar passport holders) are also required
