SHANGHAI, Jan 21 (Reuters) - China shares soared on Wednesday, with the Shanghai Composite Index producing its biggest one-day percentage gain in more than five years as investor confidence continued to recover after Monday's plunge.

Haitong Securities hit its 10 percent daily trading limit while CITIC Securities climbed 7.7 percent. Both stocks plummeted by the maximum daily limit of 10 percent on Monday after falling foul of the regulators on Friday following investigations into margin trading.
