The Portuguese governor João Maria Ferreira do Amaral had adopted a confrontational stance towards the Chinese, as displayed in the earlier revolt of the faitiões (October 1846). In early 1849 he proposed to extend a road from the walls of the city to the Chinese border. This required the relocation of some Chinese graves. Further, he ordered Chinese residents within the walls to pay taxes to the Portuguese authorities and no longer to the imperial mandarins.
