Losers outnumbered gainers by 693 to 280 in Shanghai and 1044 to 497 in Shenzhen.

While the oil sector, which covers 24 firms, gained 1.11 percent against heavy pressure across broader indices, accompanied with steadier global oil prices.
Shares were mired in negative territory during the whole day, with losses accelerating shortly after lunch, before finally narrowing to a 0.81-percent loss following several attempts to climb up.
