Condition A tells us that college students who plan to go to Million Kwai Garden have experience in learning piano.
B condition tells us that Xiao Ming doesn't want to go to the million sunflower garden.
Condition C tells us that Xiaojun can't play the piano, and he is one grade higher than the college student who went to Zhou Pu Garden.
Next, we analyze the scenic spots one by one:
Million sunflower garden:
According to Condition A, college students who go to Wankui Garden should be able to play the piano. But according to condition B, Xiao Ming doesn't want to go to Wankui Garden, so Xiao Ming won't be the one who plans to go to Wankui Garden.
Baomo Garden:
Because there is no mention of the relevant situation of Baomo Garden, it is impossible to draw a conclusion.
Zhou Pu Garden:
According to Condition C, college students who go to Zhou Pu Garden are one grade lower than Xiaojun who can't play the piano.
Based on the above inference, Xiao Ming doesn't want to go to Wankui Garden, so Xiao Ming may be the one who intends to go to Zhou Pu Garden.
To sum up, according to the given conditions, Xiao Pei intends to go to Baomo Garden (impossible to infer), Xiao Ming intends to go to Zhou Pu Garden, and Xiao Jun intends to go to Wankui Garden (because he can't play the piano, he won't choose Zhou Pu Garden). It should be noted that Xiao Pei's choice cannot be inferred from the information given in the topic.
