Hi Ahmed,
Thanks for suggestion. We’ll consider it. As for 怎么也不, let me explain it a bit here:
【怎么】
We use WH words to indicate “every”. For example,
我谁都喜欢 [Wǒ shéi dōu xǐhuān.] I like all of them (people).
我什么都喜欢 [Wǒ shénme dōu xǐhuān.] I like all of them (things).
我什么时候都有空 [Wǒ shénme shíhòu dōu yǒu kòng.] I am available all the time.
【也】
We use 也 or 都 to strengthen the intonation. While 都 is used in both negative and positive statements, 也 is only used in negative statement. For example,
我谁也不喜欢 [Wǒ shéi yě bù xǐhuān.] I don’t like anyone.
我什么也不要 [Wǒ shénme yě bùyào.] I don’t want anything.
我怎么也回答不出来 [Wǒ zěnme yě huí dā bù chūlái.] No matter how hard I tried, I couldn’t answer it.
我怎么也做不完 [Wǒ zěnme yě zuò bù wán.] No matter how hard I tried, I couldn’t finish it.
