These are some things about different cultures which I’ve picked up over the years.. they are all potential generalisations so take everything with a grain of salt!
Dumplings for Spring Festival (in the North)
Red envelopes with money in them during Spring Festival
Long noodles for long life – sometimes one massive noodle in a bowl (for birthdays?)
Sport and military training are compulsory at university
Public holidays for all religions, and for days when independence was fought for and won
Free public universities, but they close for around two months each year because there are political student parties that fight and cause the university to close temporarily.. students are still allowed to use the university though, and it allows some dedicated students to get ahead. But still, it took Chandan an extra 20 months to finish his degree. But, people are happy to accept that because it is still free!
Some want to not allow the student political groups because of the trouble that they cause, but they were so important in the independence of Bangladesh and have proven their place. It is at least thought that the groups should be separate from the major political parties.
