HISTORY (13)
Philip Y.L. Woo
The following is a brief
survey of some basic facts.
about China from 1898 to 19119
THE HUNDRED. DAY REFORM, 1898
A.Reasons:
17China's defeat in the
Sino-Japanese War (1894-
95)
2.New demands of Western
Powers in the Scramble for Concessions (1896-99'). B.Radical reformers:
1.Kang Yu-wei (1858-1927)= scholar-gentry background and education, explained China's tradition in. radically new ways, aroused anger of other scholars.

Solid C is white when cold but yellow
when hot.
Solid C can be converted to by
passing carbon monoxide, but not hydrogen, over heated slid Cl Question 20

(a) Give the chemical names of the substances A, B, C, D, E, and G.
(b) Give the equations for all the reactions involved.
(c) What is gas X!
If gas X dissolves in water, what is the effect of the solution on a litmus paper?,
(a) hat can be seen when an onia solution is added to solution
3?
Question 21
(a) explain, with the help of
ionic equationis, each of the follwoing observations. (1) When a copper wire is
placed in aqueous bilver nitrate solution for some time, it becomes coated- with white crystalline solid and a pale blue solution is resulted.
(ii) When carbon dioxide is pened into lime w ter, white precipitate is seen. but it dimelves again when an excess of carbon dioxide is pashed into it. (iii) Wien chlorine gas is.
passed into the colourless potassium iodide solution, it gradually becomes brown and finally, dark grey solids appear at the bot- tom of the test-tube. (iv) When acidified silver
nitrate is added to a metallic chloride solu- tion, white precipitate is observed. The precip - itate disappears when an excess of anconia solution is added to the mixture.
(b). An element called europium,
symbol Eu, exists naturally as a mixture of equal quan- tities of two isotores. They may be represented by the
2.Liang Ch'i-ch'ao (1873-
1929),K¦ang's follower. 3.Tan 5su-t'ung (1865-46),
advocating deep western- ization,freedom and equality.
Political activities of reformers:
A
1. Reform societies were set
up, journals for reform
were published; memorial
sent by scholars at
Peking to the dynasty. 2.The reformers.in power.
the Hundred Days of Reform (June 1898) a.Kuang-hau Emperor lent
support to reform. b.Reform edicts issued:
education and examina- tion updated, army re- organized,central government administra- tion to be made more. efficient, plans for local government. c.Overthrow of reformers:
reformers asked Yuan Shih-k ai (1859-1916) to capture press Dowager, but Yuan betray- ed reformers. Tz'u-hsi (Empresa Dowager) came back to power, Kuang- hsu lost influence. Fate of reformers: escape of Kang Yu-wei and Liang Ch'i-chao, six other reformers
(including Tan Ssu- tung) were killed.
d. Reasons for failure of
reform::
1)reform measures
aroused oppositions. from corrupt officials & Manchus (who feared Chinese dominance). )Objections of Confu- cian conservatives. 3)Lack of planning & far-sightedness, on the part of reformers. D. Continuity of reform ideas:
1.Moderate reform continued.
e.g. Chang Chih-tung's reform program. Chang's
idea, "Chinese learning as
the foundation; Western learning as the means" very popular.
2.Yen Fu translated Western ideas, in support of full- scale westerhization, liberalism, need to
strengthen China. Beginn- ing of Chinese national- ism.
THE BOXER UPRISING & LATE CHLING REFORM 1900-1911
A. Boxer Rebellion(1898-1901)
1.Origins of Boxer Movement:
a.Secret societies b.Anti-foreign ideas and
acts
b.hatred toward missionary
activities & anti- Christian ideas.
2. Different policies of
Ch'ing officials toward- Boxers:
a. Encouragement from
Manchu & reactionary officials.
b. Suppression by other
officials like Yuan
Shih-k'ai (in Shantung -in 1899)
ment in areas under pro- Boxer officials.
d. Boxers in Peking, attack- ing foreign legations. Tz tu-hai encouraged Boxers, declared war on all foreign: Powers. f.Viceroys like Li Hung-
chang & Chang Chih-
tung in the south
remained neutral..
3. Foreign expeditionary
force to Peking:
a.Defeat of Boxers & fall
of Peking
b.Escape of emperor &
Tzju-hei from Peking
4.Boxer Protocol 1901:
a.China had to pay large
indemnity.
b. Punishment of pro-Boxer
officials
5. Effects of Boxer Uprising a.China's national rights
further violated by
harsh Frotocol. /
b. Tzu-hsu realised need..
for reform, thus the Late Ch'ing reform (1901-11)
c.Political decentraliza- tion,as viceroys dis- obeyed the dynasty.
d. More people turned to welcome revolution, e.China's determination to fight foreigners checked foreign imper- falism, end to the Scramble for Concessions. e.Tensions between Japan & Russia in Manchuria, since Russla occupied the place during Boxer disturbances,
B.The Late Ch'ing deform"
(1901-1911)
1.Military reforms & power
of Yuan Shih-k'aig
a. Further modernization.
of Chinese army... b.Tzu-hai and Kuang-hsi
died in 1908, Yuan forced to retire.
Educational reforms: a.Abolition of civil
service exam system in 1905:
b.spread of modern schools
& Western studies e.Founding of Peking
University.
3.Political reforms:
a. Constitutional movement
due to demand in the provinces impact of Japanese victory in the Russo-Japanese War (1904-
05).
b. In 1908,creation of
local self-governments, in 1909, creation of provincial assembles, in 1910, creation of national assembly formation of the first cabinet in 1911.. Reasons for failure.
a. Education reforms gave
rise to patriotic students &
intellectuals hostile to the dynasty. b.Political reforms led
to further political decentralization and ⠀ disloyalty in provinces. c.Military reforms creat-
ed regional forces nearly independent of Peking's control. d.Tz'u-hsi was insincere. e. Really able officials were lacking to carry out reform f.The Dynasty's economic
conditions were poor. g.foreign imperialism
had harmful effects on China
h.Conservatism was strong.
