Ink wash painting, also known as literati painting, is an East Asian type of brush painting that uses black ink—the same as used in East Asian calligraphy, in various concentrations.

For centuries, this most prestigious form of Chinese art has been practiced by highly educated scholar gentlemen or literati.

Names used in the cultures concerned include: in Chinese shuǐ mò huà, in Japanese sumi-e or suibokuga, in Korean sumukhwa, and in Vietnamese tranh thủy mặc.

Mokuan, one among many Japanese monk-painters who go to China for extended periods and thus become the direct inheritors of Chan painting traditions, prominently features portrayals of the free and uncommitted Chan saints: eccentrics such as Putai (Pu-tai), Hanshan (Han-shan), and Shide (Shih-te).

He is one of the first artists in Japan to use the newly introduced suiboku style.

Mokuan dies in 1345.

The several divisions of the old Mongol Empire are in a state of gradual decline.

The Yuan dynasty in China is seeing the first seeds of a resistance that will lead to its downfall.

The Golden Horde to the north is besieging Genoese colonies along the coast of the Black Sea.

Jani Beg had commanded a massive Tatar force that attacked the Crimean port city of Kaffa in 1343.

The siege had been lifted by an Italian relief force in February.

In 1345, Jani Beg again besieges Kaffa; however, his assault is again unsuccessful due to an outbreak of the Black Plague among his troops.

It is thought that Jani Beg's army catapulted infected corpses into Kaffa in an attempt to use the Black Death to weaken the defenders.

Infected Genoese sailors subsequently sail from Kaffa to Genoa, introducing the Black Death into Europe.

Swedes continue early stages of their emigration to Estonia, which will continue in the coming decades.

Estonian rulers also manage to crush the St. George's Night Uprising in 1345 after a two-year struggle.

The Grand Duchy of Lithuania changes hands from Jaunutis to his brother Algirdas in a relatively bloodless shift of power, and Lithuania continues its skirmishes with its northern, Estonian neighbor.

Algirdas deposes Jaunitis in 1345, from which time he and a younger brother, Kestutis, reign jointly; the former ruling the western lands from Vilnius, and …

…the latter ruling the east from Kaunas.

Serbia, Bulgaria, and the Roman Empire are the main forces in the Balkans in the 1345.

Constantinople, though powerful, is in a state of decline, with an ongoing civil war between emperors John V Palaiologos and John VI Kantakouzenos, although in 1345, the tide begins to turn toward the latter.

The Zealot commune in Thessalonica enters a more radical phase.

Stefan Uroš IV Dušan of Serbia proclaims himself Tsar of the new Serbian Empire and continues his efforts at expansion, quickly conquering Albania and other surrounding areas within the year.

Turks clash with Greeks, Serbs, and Cypriots at sea and in the islands of Chios and Imbros.

The Empire's precarious situation at this time is evidenced by the fact that they do not have enough soldiers to protect their own borders, but hire mercenaries from the Serbs and the Ottoman Turks.

The Ottoman Turks, having establishing their Muslim principality in northern Anatolia, continue moving westward, crossing into Thrace in Europe by 1345 at the invitation of self-procaimed emperor John IV Kantakouzenos, who requires their assistance to support his rebellion against the regency for fourteen-year-old Emperor John V Palaiologos.
