Your best option is to apply for a visa as the spouse of a French national. Your TIE won't really help you unless you have been resident in Spain for at least 5 years and there can be other complications. As the spouse of a French national, you're more or less automatically issued a visa.

Now, the one complication is that you need to have "transcribed" your marriage (translation: they need to register the fact of your marriage on your husband's birth record). If you haven't done this already, it can be a lengthy process. You need to apply for a "livret de famille" through the French consulate in the country in which you were married, get an official copy of your marriage certificate, your birth certificate, your husband's French i.d. card/information and a couple further documents.

If you've already got the livret de famille, just contact the local French embassy to see whether you apply there or through a visa agency and what documents you'll need for the application.

Once you get to France, you register with the OFII (one of the nicer French administrative offices) and there is a sequence of appointments, classes (basically on "how France works") and an assessment of your French abilities that you need to renew your residence permit at the end of your first year in France. But it's all pretty routine to get through.

Actually, if you've been married for at least 4 years (I think it is) you could simply apply for French nationality by marriage - except that that takes a good year to process once the paperwork is all in.

An EU residence card won't do all that much for you - and honestly, the spouse visa is the quickest and most reliable way to get a visa (especially since you already have the livret de famille sorted out).

If you have already done the full "contrat d'integration" drill you can always ask if some or any of your certificates might still be valid (as long as you still have them). Have you lived in France before? Usually you can't carry over the integration stuff - but hey, you never know until you ask. But for the time being, having that livret de famille in hand means the visa process will be about as simple as it gets.

No, the EU Freedom of Movement stuff for the "close family member" of an EU national specifically doesn't apply to an EU national bringing their spouse to their home country - as here, with a French national moving to France. The flip side of that is, however, that a spouse visa can only be refused if the non-EU spouse is considered to be a "threat to national security or public order" or if they refuse to learn French.

As long as they have their livret de famille, which Sofia indicates they have already, it should be a matter of days, perhaps a week or two, to get the spouse visa, which is definitely the "A ticket" for visas - full work and other privileges, though she will have to work her way through the various integration meetings set up by the OFII. But even those can be useful - in fact some of us actually wish we could have had something like that when we first arrived.

Although I don't think China recognizes dual nationality, so the OP would have to give up their Chinese citizenship if that's the case.

Still, I think the one year (plus) processing time is probably the main sticking point. Not nearly in time to move to France in September.
