Tea processing full oxidation and producing "Gongfu" black tea (工夫紅茶). When there was insufficient sun and temperatures were low, the withered leaves would be processed indoors in warmed rooms and allowed to fully oxidize, then smoked dry over pine fires thus producing lapsang souchong. According to oral traditions of the region, the discovery of lapsang souchong processing was due to military troops passing through a Wuyi's tea factory during the last years of the Ming Dynasty, causing delays to tea leaf processing thus resulting in a completely oxidized leaf that the producer salvaged by drying over a fire built from pine branches.
Dual abelian variety soon as André Weil had given a general definition of Albanese variety. For an abelian variety "A", the Albanese variety is "A" itself, so the dual should be "Pic"("A"), the connected component of what in contemporary terminology is the Picard scheme. For the case of the Jacobian variety "J" of a compact Riemann surface "C", the choice of a principal polarization of "J" gives rise to an identification of "J" with its own Picard variety. This in a sense is just a consequence of Abel's theorem. For general abelian varieties, still over the complex numbers, "A" is in the same
