I realized my adviced is a little radical,but I still think Asian should have something new and something based on prejudice and stereotypes should be changed in the future.
=====================================================================================
First,sorry for my poor English.
Many of their units is based on prejudice and stereotypical(such as flying crow，siege elephant and sowar,etc.),they should be replaced by the units more representative and more realistic units.I have some advices for it,only for reference.
Chinese:
Chinese can send a card called “Westernization Movement” in age 4(cost 1000 gold),it will replace ancient artilleries with modern units(Shenwei General cannon will replace Flamethrower,it is a kind of artillery similar to Falconet but cheaper and weaker;Weiyuan General Mortar will replace HandMortar,it is stronger than the HandMortar but it will cost 3 pops;Krupp Field Cannon will replace the Flying Crow，it has 28 range,have a good fire rate but weaker to the Heavy cannon,cost 6 pops.The Confucian Academy will no longer automaticly train Flying Crow,train or send card of Krupp Field Cannon will cost gold,The Confucian Academy can research a technology called “revivalism”,it can make the banners cheaper and weaker).This card will also send a wagon,it can be deploy to Training Ground,it can only keep on Training Ground at the same time but if it has been destoryed by the enemies,it can be rebuild by Villagers.This place can train Xiang Army(composed of New Army private and New Army Mauser Gunman),Huai army(composed of New Army Mauser Gunman and New Army Field cavalry)，Gan Army(composed Gansu hui army and New Army Field cavalry),and the Krupp Field Cannon.
The New Army private is a kind of musketeer,New Army Mauser Gunman(they use Gewehr 1888,not Gewehr 1898.It is called Mauser 1888 in China just because some cunning businessmen,lol) is a kind of skirmisher,New Army Field cavalry is a kind of dragoon but stronger then the normal dragoon,Gansu hui army is a short range,less damage skirmisher but have a Terrifying melee damage.All units trained in the Training Ground will cost gold and export.The Training Ground has a technology called “Xiaozhan military training”(cost 1000 export and 1000 gold),it will make the units trained in the Training Ground cost much more gold and food instead of cost export,this technology will also make the Training Ground train unit separate,no longer in a group,and this technology will make this units stronger.The Chinese can train Ironclad after sent this card.
Japanese:
Japanese can send a card called "Shoin Yoshida” in age 4(cost 1000 gold),it will make the "Meiji restoration"cost 1000 gold and 1000 export.After Meiji restoration,the town center will have two new technology called “Shokusann Kougyou” and "Meiji Military Reform“(both of the two technologies will cost resources),the “Shokusann Kougyou” will make villager collect resource significantly faster but decrease their hitpoint.The "Meiji Military Reform“ will make all the ancient units become modern units.Yumi Archer will become Saga repeating rifleman(skirmisher), Ashigaru Musketeer will become Jotouhei(musketeer),Samurai will become Batoutai(melee unit), Naginata Rider will become Toyo cavalry(similar to Hussar),Yabusame will become Saga Carbine Cavalry.Flaming Arrow will become Armstrong field cannon(similar to light cannon,but fire faster and the range is 30 not 32),Morutatu will become “Baby of Osaka”(similar to the Mortar but can cause devastating damage to infantry,cost 6 pops).Daimyo will become General(Iwao Oyama,Maresuke Nogi,Gentaro Kodama and Aritomo Yamagata,similar to the War of Liberty).The Japanese can train Sloop and Steamer after research "Meiji Military Reform“.
Indian:
Indian can send a card called “Mughal Military Reform” in age 4(cost 500 gold).It can make the ancient units become modern units.Rajput will become Nagas(melee unit),Sepoy will become Bengal musketeer,Gurkha will become Hillmen Light Infantry(skirmisher). Caravanserai will no longer train camels and elephants,they will have Ahadi(similar to Cuirassier but they are weaker and cheaper,cost 2 pops) and Wala Shahi(similar to the Ruyter but they are stronger).indian can train and upgrade elephant in Castle, Flail Elephant will become zarb zan(similar to the Catbang cannon but can cause more damage to the buildings,cost 3 pops),Siege Elephant will become to the Fath Gusha(it is a kind of Heavy Cannon weaker then the Siege Elephant when fight against artilleries and buildings but stronger then the Siege Elephant when fight against infantry,cost 6 pops).All of those new units will have their own mansabdars.
