Q: Passage: Fortunately for Joseon, instead of invading them immediately, from late 1633 to mid 1635, Later Jin set out to conquer nearby Ming and Mongolian territories with particular attention to Chahar Mongol tribe. While this period should have been the opportunity for the Joseon government to strengthen their defense, political situations stood in their way. First, a Ming envoy, Lu Weining visited Joseon in June 1634 to preside at the installation ceremony of their crown prince. Unfortunately for Joseon, the envoy requested excessive amount of bribe in return for the ceremony. In addition, quite a few merchants who attended the envoy sought to make a huge fortune by forcing unfair trades upon their Joseon counterparts. This envoy visit eventually cost Joseon more than 100,000 taels of silver. King Injo, who had successfully accomplished installations of both his parents and son with help from Ming, now attempted to relocate the memorial tablet of his late father into the Jongmyo Shrine. As his father has never actually ruled as the king, this attempt met with severe opposition from government officials, which lasted until early 1635. Adding to this, the mausoleum of King Seonjo was accidentally damaged in March 1635 and the political debate about its responsibility continued for the next few months. These political gridlocks prohibited Joseon from taking enough measure to prepare for a possible invasion from Later Jin. 
Question: How many months after Lu Weining visited Joseon to preside at the installation ceremony of the crown prince was the mausoleum of King Seonjo accidentally damaged? 
Answer type: Number 

A: 9.

Q: Passage: The Cham also requested Ming China to intervene by helping bring the Vietnamese back in line by force and demarcate the border between Champa and Vietnam. China, however, only verbally rebuked the Vietnamese for its incursion, which the Vietnamese ignored, proceeding with its attack and plan to destroy its rival. The Vietnamese then carried out its campaign. On November 28, 1470, Le Thanh Tong formally launched his attack as a 100,000-strong Vietnamese naval expedition set out that day, followed by another Vietnamese army consisting of 150,000 men on December 8. The Vietnamese army was reorganized to copy the Chinese army, armed with gunpowder weapons. Le Thanh Tong raised a total of 300,000-strong army in the battlefied and, significantly outnumbering the 100,000-strong Cham army. This came at a massive financial cost since it drained the Vietnamese treasury of 1,000 gold liang each day. However, it decisively won the war. 
Question: After formally launching an attack, how many days later did Le Thanh Tong increase his army? 
Answer type: Number 

A: 10.

Q: Passage: Around 50,000 of the former czar's army troops were stationed in Finland in January 1918. The soldiers were demoralised and war-weary, and the former serfs were thirsty for farmland set free by the revolutions. The majority of the troops returned to Russia by the end of March 1918. In total, 7,000 to 10,000 Red Russian soldiers supported the Finnish Reds, but only around 3,000, in separate, smaller units of 100-1,000 soldiers, could be persuaded to fight in the front line. The revolutions in Russia divided the Soviet army officers politically and their attitude towards the Finnish Civil War varied. Mikhail Svechnikov led Finnish Red troops in western Finland in February and Konstantin Yeremejev Soviet forces on the Karelian Isthmus, while other officers were mistrustful of their revolutionary peers and instead co-operated with General Mannerheim, in disarming Soviet garrisons in Finland. On 30 January 1918, Mannerheim proclaimed to Russian soldiers in Finland that the White Army did not fight against Russia, but that the objective of the White campaign was to beat the Finnish Reds and the Soviet troops supporting them. The number of Soviet soldiers active in the civil war declined markedly once Germany attacked Russia on 18 February 1918. The German-Soviet Treaty of Brest-Litovsk of 3 March restricted the Bolsheviks' support for the Finnish Reds to weapons and supplies. The Soviets remained active on the south-eastern front, mainly in the Battle of Rautu on the Karelian Isthmus between February and April 1918, where they defended the approaches to Petrograd. 
Question: What 1/10 of a decade did around 50,000 of the former czar's army troops were stationed in Finland? 
Answer type: Date 

A:
{'day': '', 'month': '', 'year': '1918'}.
