Are there any activities for students & foreigners over the summer? :(

:) Hi everyone.
I'm a 3rd student studying tourism and living in the outskirt of city. I have just done my 3rd years in the university. My parents said I should come back home to take a rest. But I still want to live in the city to discover a lot of interesting things.  I don't still have any plan in this summer yet. :( Could you please recommend any activities or places for me in Hanoi? If you have, may i join it? Thank you so much! Looking forward to getting your advices!

i thought it was always summer here.
