Iam amazed by the poor knowledge that you have regarding India.
Please improve ur Chinese English . Chinese kille any language during usage ..and u too are doing that..like u have written ,, "PRACTICALE" and "ARE" instead of "OUR".
Regrading the wall,,,if u appreciate the love for architecture,,India has much more than that "Protective device". Hope you know about the TajMahal..which symbolises LOVE in world level..succeds architecture in true sense.
On top of that ,,Indians are brave hearted enough to plunge into any danger.India was invaded greater number of times,,compared to chinese.
Does not your history book contain about the Indo-China war?? The support of Maoist activites comes form none other than China. The main motto of chinese goods that they produce damages economy of any country. Quality,,its the classless. Perhaps NOBLE winning for their malfunctioning.
An honest advice, learn about India first . India was ,,is ,,and will always be a world teacher.
