Where can we find the most frequent combination of two Chinese words (搭配)?
I know there are many excellent learners' dictionaries and collocations dictionaries in English, but sadly Chinese lexicography doesn't seem to have done a good job.
Some resources that might help you:
1）search 汉语搭配词典 here on http://www.ucdrs.superlib.net
2）Look up in general dictionaries
现代汉语词典（download it here https://b-ok.asia/book/3583521/fc4154）
（台灣）教育部重編國語辭典：http://dict.revised.moe.edu.tw/cbdic/search.htm
learner's dictionary: 《现代汉语八百词》
3）Use 语料库（Corpus）
