You can't become Chinese because you have married with Chinese. Only a person who has lived 5 years in China and is a desirable person may obtain Chinese Resident Visa(https://www.travelchinaguide.com/embassy/visa/apply.htm#resident). In practice it seems that very few people are able to achieve this status. Unless you have made massive investments which have generated substantial profit to China and you have good connections with the establishment, it seems you are unlikely to succeed.
