no, learn history dude. it is your fault, too. prior the french conquest of vietnam, you rather thought how to weaken and harm Vietnam than cooperation to act against our enemy. we paid tributes but you failed to protect Vietnam. but anyway I understood your behavior. China and Vietnam were political rivals, held different view on the region. well not much different to today.
the time frame you mention was during the period of confrontation of the competing Viet dynasties the Nguyen and Trinh, after the fall of the Le. the civil war period. it has little to do with Qing China. not 19 but 18 century.
