Comparissons in Chinese

The basic structure for comparison 比 bǐ is: 
A + 比 + B + Adjective
For example: 
  •  我哥哥(A) 比 我(B) 高(Adj)。(My older brother is taller than me.)
  • 这个公园(A) 比 那个公园(B) 漂亮(Adj)。(This park is prettier than that park.)
But in the real conversation, we may add more details when we compare.
You can add “degree,” like:
  • “Wow! This one is MUCH bigger than that one.”
  • “I am just A LITTLE shorter than him.”
  • “He is 4 years older than me.”
You can add “degree” in the end of the sentence. So the structure is:

A + 比 + B + Adj. + Degree

For example:
  • 我哥哥(A)    比 我(B)   高(Adjective)   得多(Degree)。(My older brother is taller than me.)
  • 我哥哥(A) 比 我(B) 高(Adjective) 五公分(Degree)。(My older brother is 5 centimeters taller than me.)
You also can add “even more” when you would like to compare 3 things. So the structure is:
C + 比 + A + 更/还 + Adj.
For example:
  • 我哥哥(A) 比 我(B) 高(Adjective), 我爸爸(C) 比 我哥哥(A) 更(even more) 高(adjective)。
