海绵不能没有宝宝多拉不能没有A梦
[hăi mián bù néng méi yŏu băo băo duō lā bù néng méi yŏu a mèng]
Refers to Doraemon, a popular cartoon character named in Japanese 'Dora', who is always with Nobita (his best friend). Here, 'spongebob (海绵宝宝)' is also used alongside creating an analogy that just like Dora cannot live apart from Nobita, these two inseparable entities must stay together for everything to work out perfectly, emphasizing on friendship or companionship.
