Basically Lin Shi is trying to explain the characters for his name. His surname is 林, which basically means forest. The character uses two 木 symbols (the character for wood), so that's why he says "A forest tree. A double wooded forest...". The Shi in his name is 實, and in the Chinese version, he's trying to say that the 實 in his name is the same character for 果實 (fruit). However, the correct character is 果实 (also pronounced shi, but different character). Hence, XiaoFei says "the fruit is wrong", because it's the wrong character.
Also, when XiaoFei says "Cold type?", I think he refers to his personality as being the more cold, withdrawn type.
Anyways, I'm not really familiar with traditional Chinese because I usually use simplified Chinese but I hope this helps ! ! I'm sorry if my explanation is a bit complicated to understand :')
