You may ask why I like this most? 

It’s a simpe way, I just checked two items to see whether it’s a good dictionary or not.

One is comparing  “二” with “两”,  these two words are always confused by Chinese learners. “二”(er) and “两” (liang) both mean the number “two” in English, but  usages are different.  “两” is used for the number under ten, while “二”  is used for the number above ten, some exceptions like “两千两百二十二”（liang qian liang bai er shi er), two thousand and two hundred twenty two, here we say “两” instend of “二” in thousand’s place and hundred’s place.

Another is looking up the measure words like “块”(kuai) and “条”(tiao).　”块”, measure word,  for sh. shaped like lumps or chuncks. E.g. ＂一块糖＂（yi kuai tang），＂a lump of sugar＂．＂条＂, measure word, used for long and thin things. E.g. ＂两条腿＂（liang tiao tui）＂two legs＂．

So if got these two items in that dictionary, and the explanations are complete and clear, that’s definitely a good dictionary.
