I don't know "the patriotic Chinese curriculum" is going to be introduced to which schools. The picture on the linked page shows the students in Chinese University of Hong Kong (CUHK) protest against the curriculum. So the curriculum will be introduced to the educational system of CUHK?
But, when we take into account that college students including CUHK students are enough wise to judge whether the Chinese propaganda is correct or not.
I think it would be crisis only when the curriculum is compulsory and introduced to elementary school or high school.(Is there possibility that it will be introduced to kindergartens?)
In Japan, the patriotic Japanese curriculum is also reviewed to make it play a role in growing patriotism in Japanese citizens' minds. Disputes over the curriculum usually result in assessment of actions taken by Empire of Japan in World War 2.
In my opinion, argument of the patriotic Japanese curriculum should be separated from that of Japanese history's assessment.
